The '''Semi First''' and '''First Six''' is a series of Japanese folding cameras in 4.5×6 or 6×6 format, made by [[Petri|Kuribayashi]]<REF> The attribution to [[Petri|Kuribayashi]] is confirmed by the {{Inquiry1943_short}}, items 1–7 and 80–1. </REF> from 1935 and distributed by [[Minagawa|Minagawa Shōten]]. There are two generations: the first models with round body ends were succeeded in 1939 by the U models with angled body ends. Later cameras have a rigid finder, with an additional extinction meter or brilliant finder on the BB Semi First. The production of the camera was continued after World War II as the '''Kuri''', and the same body formed the basis of the [[Petri (Semi)|original Petri]] (today called "Petri Semi" and treated in a separate page).

Other Kuribayashi cameras with a similar name are dealt with in separate pages: the [[Auto Semi First]] is a coupled-rangefinder model and the [[Baby Semi First]] is a compact 4.5×6 folder of different construction. See also the [[First Six (postwar)|postwar First Six]] made by [[Tokiwa Seiki]].

== First generation: rounded body ==
=== The original Semi First ===
The '''original Semi First'''<REF> This model is called "Semi First A" in Baird, p.69 of ''Kuribayashi-Petri Cameras'', and {{MK}}, p.576, but this is a confusion. </REF> (セミファースト) was released in mid-1935.<REF> The earliest advertisement mentioned in {{Kokusan}}, p.339, is dated June 1935. </REF> It is a vertical folder, close copy of the [[Perle|1932 Perle]] by [[Welta]], notably for the folding struts. It has rounded body ends and a folding optical finder. The advance knob and folding bed release are both placed at the bottom right, as seen by the photographer holding the camera horizontally. The back is hinged to the left and the back latch is covered by a leather handle. The name ''Semi First'' is embossed in the front leather in a cursive style.<REF name="embossing"> Many surviving examples do not have their original covering. </REF>

In advertisements dated June and July and December 1935, it was offered in two versions:<REF> June 1935: advertisement published in {{ACA}}, reproduced in Baird, p.70 of ''Kuribayashi-Petri Cameras''. July and December 1935: advertisements published in {{ACA}}, reproduced in {{Kokusan}}, p.85. </REF>
* Toko f/6.3 lens, [[Magna]] shutter ({{yen|43|1935}});<REF> The examples pictured in {{SUG}}, item 1048, and ''Omoide no supuringu-kamera-ten,'' p.20, either correspond to this version or to the equivalent version of the Semi First B. </REF>
* Toko f/4.5 lens, [[Magna]] shutter ({{yen|50|1935}} in June and July, {{yen|52|1935}} in December).
The Magna shutter gives T, B, 25–100 speeds set by a small wheel at the top. It was made by [[Hattori|Seikōsha]]. The Toko lenses have three elements and were made by [[Tōkyō Kōgaku]].<REF> Confirmed in the {{Inquiry1943_short}}, lens item Lb20 and Lc1. </REF>

A later advertisement added the following two lens and shutter combinations:<REF> Undated advertisement, reproduced in Baird, p.71 of ''Kuribayashi-Petri Cameras''. </REF>
* Radionar f/4.5 lens, [[Rulex|Rulex B]] shutter (¥60);
* Toko f/4.5 lens, [[Seikosha (shutter)|Seikosha]] shutter (¥85).<REF> The example pictured in Tanaka, p.78 of {{KKS}} no.8, with an additional brilliant finder, probably coresponds to this version, but it might also be a Semi First A. </REF>
The Rulex B gives T, B, 5–150 or T, B, 5–200 speeds and the Seikosha gives T, B, 1–250 and has a self-timer.<REF> These combinations are confirmed by {{Kokusan}}, p.339, for the original Semi First. </REF>

Another advertisement dated July 1936<REF> Advertisement published in {{AR}}, reproduced in Furukawa, p.22 of {{CCN}} no.277. </REF> mentions a patented film advance (パテント巻取), perhaps an early occurrence of the exposure counter of the Semi First A (see below).

It is also said that a [[brilliant finder]] was available on special order.<REF> Tanaka, p.78 of {{KKS}} no.8. </REF>

|}The '''original First Six''' (ファーストシックス) was announced in late 1936.<REF> The earliest advertisement mentioned in {{Kokusan}}, p.339, is dated December 1936. </REF> The First Six has an index above the advance knob, serving as a manual exposure counter and advance indicator. This device was needed because the paperback of [[120 film]] was not yet marked for 6×6cm format when the camera was released.

The index consists of a small plate hinged to the body, which can be moved out of the way to lift the advance knob for film loading. This plate has two holes, corresponding to concentric scales engraved on a rotating disc placed in the advance knob. The outer scale is graduated from 1 to 8 and the inner scale is graduated from 9 to 12. The graduations are not evenly spaced, to compensate the variation of the spool diameter when the film is wound. More than one turn is needed to advance one frame for the eight first pictures, then exactly one turn to go to the ninth exposure, and less than one turn for the remaining pictures, hence the two scales. The single red window at the top left of the back, protected by a horizontally sliding cover, is used to set the position of the first exposure. Once the number 1 of the film paper backing appears in this window, the user needs to turn the disc until the number 1 appears inside the index hole.

The folding bed release is now on the other side of the body, to the right of the viewfinder, to leave space to the exposure counter index. The finder is adapted for the 6×6 picture size, with a thinner front frame. The name ''First Six'' is embossed in the front leather in a cursive style.<REF name="embossing" /> The [[Adler Six|Adler VI]] sold from 1938 by [[Asahi Bussan|Asahi Kōgaku Kōgyō]] might be a rebadged version of the original First Six.

The Semi First was simultaneously replaced by the Semi First A and B.<REF> Baird, pp.69–73 of ''Kuribayashi-Petri Cameras'', and {{MK}}, p.576, are mistaken about the Semi First A and B. </REF> The '''Semi First A''' (セミファーストA型) has a manual advance indicator and exposure counter device, like the First Six but adapted for sixteen 4.5×6 exposures, with three concentric scales. The hinged index plate is apparently replaced by a simple dot on the body. Less than one turn is needed for each frame, down to a quarter of a turn for the last pictures. In addition to the exposure counter device, the camera also has two red windows near the top of the back, protected by covers retracted by a common lever. The '''Semi First B''' (セミファーストB型) is a cheaper version without the exposure counter. It is said to differ also by the red windows and by the body covering.<REF> The advertisement dated December 1936 reproduced in {{Kokusan}}, p.86, says that the Semi First B differs by the film winding, red windows and body covering. The advertisement dated September 1937 reproduced on the same page says that the Semi First A alone has the exposure counter. </REF> The differences between the original Semi First and the Semi First B are unknown.

The folding bed release was switched at some time from its initial position next to the advance knob to the other side of the body, on the right of the viewfinder. However this change occurred after the introduction of the models A and B, and actual examples of the Semi First A have been observed with the button on either side.<REF> Examples observed in online auctions. </REF> The change was perhaps the result of a standardization of the parts with the First Six.

In an advertisement dated December 1936,<REF> Advertisement published in {{ACA}}, reproduced in {{Kokusan}}, p.86. </REF> the First Six was announced only and the Semi First was offered in the following versions:
* Semi First B, Toko f/6.3 lens, [[Magna]] shutter ({{yen|38|1936}});<REF> The examples pictured in {{SUG}}, item 1048, and ''Omoide no supuringu-kamera-ten,'' p.20, either correspond to this version or to the equivalent version of the original Semi First. </REF>
* Semi First B, Toko f/4.5 lens, [[Magna]] shutter ({{yen|45|1936}});
* Semi First A, Toko f/6.3 lens, [[Magna]] shutter ({{yen|43|1936}});
* Semi First A, Toko f/4.5 lens, [[Magna]] shutter ({{yen|52|1936}});<REF> This version is pictured in {{SUG}}, item 1049, with the folding bed release on the finder side. </REF>
* Semi First A, Radionar f/4.5 lens, [[Rulex|Rulex B]] shutter ({{yen|60|1936}});
* Semi First A, Toko f/4.5 lens, [[Seikosha (shutter)|Seikosha]] shutter ({{yen|85|1936}});<REF> This version is pictured in [http://ranzosha.web.fc2.com/d030semifirst.html this page by Ranzōsha] with the folding bed release on the advance side, and has been observed in an online auction with the folding bed release on the finder side. See also the example pictured in Tanaka, p.78 of {{KKS}} no.8, with the folding bed release on the advance side and an additional brilliant finder, probably an original Semi First. </REF>
* Semi First A, Toko f/3.5 lens, [[Seikosha (shutter)|Seikosha]] shutter ({{yen|98|1936}}).<REF> This version is pictured in {{SUG}}, item 1057 (folding bed release on the advance side), where it is misidentified as a "First Semi Model-U". It has also been observed in an online auction, with the folding bed release on the advance side and the front finder frame in silver instead of black finish. </REF>
The advertising pictures show a Semi First A with f/3.5 lens and Seikosha shutter. One of these pictures is retouched with a ''FIRST SIX'' inscription on the camera's front leather, pretending that it is a First Six: this can be told by the shape of the finder and of the exposure counter.

In an advertisement dated April 1937,<REF> Advertisement published in {{ACA}}, reproduced in {{Kokusan}}, p.86. The prices are barely legible. </REF> the Semi First A with Magna shutter were no longer offered and the following Semi First versions were added to the ones listed above:
* Semi First B, First f/4.5 lens, [[Rulex|Rulex D]] shutter ({{yen|45|1937}});
* Semi First B, First f/4.5 lens, [[Rulex|Rulex B]] shutter ({{yen|50|1937}});
* Semi First B, First f/4.5 lens, [[Rulex|Rulex A]] shutter ({{yen|55|1937}});
* Semi First A, First f/3.5 lens, [[Rulex|Rulex B]] shutter ({{yen|60|1937}}).
The First f/4.5 and f/3.5 lenses have three elements and they were certainly supplied by [[Tokiwa Kōgaku]].<REF> Confirmed for year 1943 by the {{Inquiry1943_short}}, lens item Lb18 and Lc2. Baird, p.25 of ''Kuribayashi-Petri Cameras'', says that the First Anastigmat lenses were assembled by Kuribayashi from elements supplied by Miyoshi, but this is apparently a mistake. </REF>

The First Six were also listed, and this time the picture truly depicts one of these:
* First Six, Toko f/6.3 lens, [[Magna]] shutter ({{yen|40|1936}});
* First Six, Toko f/4.5 lens, [[Magna]] shutter ({{yen|46|1936}});
* First Six, First f/3.5 lens, [[Rulex|Rulex B]] shutter ({{yen|60|1937}});<REF> This version is pictured in {{SUG}}, item 1050, misidentified as a "Semi First II". The shape of the finder and of the exposure counter index shows that it is a First Six. </REF>
* First Six, Toko f/4.5 lens, [[Seikosha (shutter)|Seikosha]] shutter ({{yen|85|1936}});<REF> This version is pictured in Baird, p.89 of ''Kuribayashi-Petri Cameras'', and in {{MK}}, p.576. </REF> 
* First Six, Toko f/3.5 lens, [[Seikosha (shutter)|Seikosha]] shutter ({{yen|98|1936}}).<REF> This version is pictured in ''Omoide no supuringu-kamera-ten,'' p.20, and in [http://simijimi.exblog.jp/12430522/ this page at Sakura-blend's blog]. </REF>

The Semi First A and First Six were later released with a First f/2.9 lens and a [[Rulex|Rulex A]] shutter (T, B, 1–200) (see below). The First Six has also been observed with a Radionar f/4.5 lens and a [[Rulex|Rulex B]] shutter (5–200, T, B), both made by [[Neumann & Heilemann]],<REF> Example pictured in [http://ranzosha.web.fc2.com/d020firstsix.html this page at Ranzōsha's website], and example observed in an online auction. </REF> and with a First f/3.5 lens in a [[Nishida shutters|Wester I]] shutter (1–200, B, T).<REF> Example observed in an online auction. </REF>

Another example of the Semi First is pictured in {{SUG}} with a First shutter giving T, B, 5–200 speeds and a First Anastigmat 75/4.5 lens.<REF> {{SUG}}, item 1051. </REF> The shutter plate is inscribed ''First'' at the top, ''FIRST WORKS'' at the bottom and has an ''F'' inside a circle on the right. This shutter certainly corresponds to the "First Type B" mentioned by Baird.<REF> Baird, pp.20 and 22 of ''Kuribayashi-Petri Cameras''. </REF> The camera has the folding bed release on the finder side, and the shape of the advance knob probably indicates that the camera is a Semi First B.

Yet another example, probably a Semi First A, is pictured in Baird with a First Anastigmat f/2.9 lens and an unnamed shutter having a ''PL'' logo on the right of the shutter plate, and inscribed ''Patents–pending'' at the top.<REF> Example pictured in Baird, p.72 of ''Kuribayashi-Petri Cameras''. </REF>

=== Introduction of the First Six S ===
The '''First Six S''' (ファーストシックスS型) was released in mid-1937.<REF> The earliest advertisement mentioned in {{Kokusan}}, p.339, is dated July 1937. </REF> It is similar to the First Six with an automatic stop advance device. The advance knob is surrounded by a frame counter ring. After the introduction of the First Six S, the original model was sometimes called '''First Six Junior''' (ファーストシックスヂュニアー). No surviving example of the First Six S has been observed so far.

In an advertisement dated August 1937,<REF> Advertisement published in {{ACA}}, reproduced in {{Kokusan}}, p.87. </REF> the following versions of the First Six S were listed:
* First Six S, First f/3.5 lens, [[Rulex|Rulex B]] shutter ({{yen|75|1937}});
* First Six S, Radionar f/4.5 lens, [[Rulex|Rulex B]] shutter ({{yen|75|1937}});
* First Six S, First f/2.9 lens, [[Rulex|Rulex A]] shutter ({{yen|100|1937}});
* First Six S, Toko f/4.5 lens, [[Seikosha (shutter)|Seikosha]] shutter ({{yen|100|1937}});
* First Six S, Toko f/3.5 lens, [[Seikosha (shutter)|Seikosha]] shutter ({{yen|113|1937}}).
The First f/2.9 lens has four elements and was certainly supplied by [[Tokiwa Kōgaku]].<REF> Confirmed for year 1943 in the {{Inquiry1943_short}}, lens item La2. </REF>

In the same advertisement, the Semi First B with Rulex D and the Semi First A with Radionar lens were no longer offered, the other prices were unchanged and two new versions were added with f/2.9 lens and T, B, 1–200 speeds:
* Semi First A, First f/2.9 lens, [[Rulex|Rulex A]] shutter ({{yen|85|1937}});
* First Six, First f/2.9 lens, [[Rulex|Rulex A]] shutter ({{yen|85|1937}}).

An advertisement dated September 1937 emphasized prominent features of the First folders:<REF> Advertisement published in {{ACA}}, reproduced in {{Kokusan}}, p.86. See also the undated advertisement reproduced in Baird, p.68 of ''Kuribayashi-Petri Cameras'', which gives a similar list. </REF>
* [[Tōkyō Kōgaku]] lenses;
* [[Hattori|Seikōsha]] shutters;
* automatic stop film advance for the First Six S;
* patented 6×6 advance system for the First Six Junior;
* patented 4.5×6 advance system for the Semi First A;
* patented brilliant finder for the [[Baby Semi First|Baby Semi First II]];
* patented red window covers for all the models.

=== Body release: the Semi First III and First Six III ===
In early 1938, a body release was added to the Semi First and First Six, on the left of the viewfinder.<REF> Date: the earliest article mentioned in {{Kokusan}}, p.339, is dated March 1938 and the earliest advertisement is dated April 1938. </REF> The First Six S became the '''First Six S III''' (ファーストシックスSⅢ型) and the First Six Junior became the '''First Six Junior III''' (ファーストシックスヂュニアーⅢ型). It is not known if the '''Semi First III''' (セミファーストⅢ型) retained the manual exposure counter of the Semi First A or not.

In an advertisement dated April 1938,<REF> Advertisement published in {{ACA}}, reproduced in {{Kokusan}}, p.87. </REF> the First Six S III and First Six Junior III were priced between ¥65 and ¥119 and the Semi First III was offered with three lens choices: f/4.5 (¥65), f/3.5 (¥119) and f/2.9 (¥103). The f/2.9 lens option was less expensive than the f/3.5 certainly because it was matched with a cheaper shutter.

One example of the First Six III is pictured in {{SUG}} with Toko f/3.5 lens and [[Seikosha (shutter)|Seikosha]] shutter.<REF> {{SUG}}, item 1053. </REF>

In an advertisement for the First Six dated July 1938,<REF> Advertisement published in {{ACA}}, reproduced in Furukawa, p.22 of {{CCN}} no.277. </REF> the [[Nishida shutters|Wester]] shutter, made by [[Nishida]], was offered as a new option. It is said that the [[Nishida shutters|Wester I and Wester II]] shutters were offered with the First lens in f/4.5, f/3.5 and f/2.9 maximal aperture.<REF> {{Kokusan}}, p.339. </REF> Both shutters give 1–200, B, T speeds, and the Wester II is distinguished by the addition of a self-timer. The shutter plate is accordingly inscribed ''WESTER–MODEL–I'' or ''WESTER–MODEL–II'' at the top.

An example of the Semi First is pictured in {{MK}} with the [[Nishida shutters|Wester Model-I]], a First Anastigmat f/4.5 lens and no body release.<REF> Example pictured in {{MK}}, p.576, with the folding bed release on the finder side. The advance knob certainly corresponds to a Semi First B. </REF>

In an advertisement dated January 1939,<REF> Advertisement published in {{ACA}}, reproduced in {{Kokusan}}, p.88. The same advertisement is reproduced in Furukawa, p.22 of {{CCN}} no.277. </REF> the Semi First and First Six were still offered without body release and called "ordinary models" (普通型), from ¥46 to ¥119. The newer models were simply called "body release type" (ボディレリーズ式), not "model III", and cost ¥75 to ¥125. The First Six S was apparently sold with body release only, from ¥85 to ¥131. The [[Nishida shutters|Wester]] shutter is prominently displayed in the middle of the advertisement. In the advertising pictures of the Semi First and First Six, the cameras have the advance knob and back latch of the later U Semi First or U First Six, but they still have rounded body ends. The Semi First also has the newer ''Semi First'' embossing in block letters. No surviving example of this transitional variant has yet been observed, and the pictured cameras are perhaps isolated prototypes.

== Second generation: angled body ==
=== The U Semi First and U First Six ===
The '''U Semi First''' (U型セミファースト) and '''U First Six''' (U型ファーストシックス) were released in early 1939.<REF> The earliest advertisement mentioned in {{Kokusan}}, p.339, is dated March 1939. </REF> They have a new body shape with angled ends and a new type of back latch, consisting of a long sliding bar with no handle. There is a body release, a new type of advance knob of smaller diameter and the release of the folding finder is larger. The U First Six has a single red window in the middle of the back, protected by a horizontally sliding cover. The U Semi First has a single red window at the bottom of the back.<REF> See for example the pictures of [http://archive.is/rd2h-ari.hp.infoseek.co.jp/JA_SEMI_FIRST_SEIKO_PIC.htm this page (archived) at Japan Family Camera]. </REF> On the 4.5×6 model, the name ''Semi First'' is embossed in the front leather in lowercase block letters, whereas the name ''First Six'' is embossed in the older cursive script on the 6×6 model.<REF> Cursive style: example pictured in Baird, pp.90–3 of ''Kuribayashi-Petri Cameras'', and in {{MK}}, p.576. </REF>

In advertisements dated March, June and July 1939, the two models were offered at the same price, in the following versions (the prices are those given in June and July):<REF> March and June 1939: advertisements published in {{ACA}}, reproduced in {{Kokusan}}, p.87 (the prices are illegible in the March advertisement).

Examples of the U Semi First have been observed with a First I shutter (T, B, 150–5), inscribed ''FIRST~MODEL-I'' at the top of the shutter plate, and a Kokka Anastigmat f/4.5 or f/3.5 lens.<REF> Examples with f/4.5 and f/3.5 lens observed in online auctions. </REF> The origin of the Kokka lens is unknown.

The list of set prices compiled in October 1940 and published in January 1941, listed the U Semi First in five versions: "U Semi First I" (¥74), "U Semi First II" (¥85), "U Semi First III" (¥121), "U Semi First IV" (¥98), "U Semi First V" (¥160), and the U First Six in five versions too: "U First Six I" (¥156), "U First Six II" (¥79), "U First Six III" (¥94), "U First Six IV" (¥128), "U First Six V" (¥160), with no further detail.<REF> {{Kakaku0141_short}}, type 3, sections 4A, 5A, 6B, 7A, 7B, 8B; type 4, sections 3, 4, 5B, 6B. </REF>

The older models were perhaps sold for some time after the introduction of the U Semi First and U First Six. The same price list also mentioned an A Semi First (A型セミファースト) in seven versions: "A Semi First I" (¥53), "A Semi First II" (¥62), "A Semi First III" (¥74), "A Semi First IV" (¥85), "A Semi First V" (¥121), "A Semi First VI" (¥160), "A Semi First VII" (¥120), and a First Six in four versions: "First Six I" (¥60), "First Six II" (¥79), "First Six IIA" (¥110), "First Six III" (¥89).<REF> {{Kakaku0141_short}}, type 3, sections 2, 3A, 4A, 5A, 6B, 7B, 8A; type 4, sections 2, 3, 5A, 6A. </REF>

A similar price list dated November 1941 does not have the A Semi First III and IV but adds a plain "U Semi First".<REF> {{Kakaku1141_short}}, type 3, sections 2, 3A, 4A, 5A, 6A, 6B, 7A, 7B, 8A, 8B; type 4, sections 2 and 3. </REF>

The folding viewfinder of the previous models was replaced by a tubular finder at some point. The new models were perhaps called "Semi First V" and "First Six V" but no original document has yet been found to confirm this.<REF> The two models are called "Semi First V" and "First Six V" in Baird, pp.74–6 and 93 of ''Kuribayashi-Petri Cameras''. The 4.5×6 model is called "First Semi Model-V" in {{SUG}}, item 1060, and "Semi First V" in {{MK}}, p.576. </REF> The finder unit is again copied from a [[Welta]] design: it is similar to the finder of the [[Perle]], [[Weltax]] and [[Garant]] models released around 1938. On the 6×6 model, the ''First Six'' embossing was changed to lowercase block letters, around the same time.<REF> Block letters: examples pictured in {{MK}}, pp.576–7. </REF>

The body edges and viewfinder assembly exist either in chrome finish or in black paint finish. The '''chrome finders''' have parallax compensation, controlled by a small sliding button on the right of the finder's base and similar to the [[Welta]] units. The '''black finders''' have no such device and certainly correspond to cheaper models; some are even lacking the body release. It is sometimes said that the black finish was adopted because of a shortage of materials,<REF> Baird, p.75 of ''Kuribayashi-Petri Cameras''. </REF> but the chrome finish was probably offered as a more expensive alternative until the end.<REF> See the specific mention of "black finish" for one of the versions listed in the {{Inquiry1943_short}} of early 1943, and the presence of black, chrome or mixed finder units on the Kuri cameras assembled after the war. </REF>

The April 1943 government inquiry on Japanese camera production mentions various Semi First and First Six models. Their naming is unclear, but the mention of black fittings tends to indicate that they correspond to the models with tubular finder:<REF> {{Inquiry1943_short}}, items 1–5 and 80–1. </REF>

The '''BB Semi First''' (BBセミファースト) is a more expensive model, first introduced in early 1940 with an '''exposure meter''', of the extinction type.<REF> The model with extinction meter is called "BB Semi First (Deluxe)" in Baird, pp.77–80 of ''Kuribayashi-Petri Cameras'', and in {{MK}}, p.577, but this designation was not used at the time. </REF> This was the first Japanese camera to have a built-in exposure meter. The tubular finder and extinction meter are grouped in a small housing in the middle of the top plate. The finder is offset to the right and is '''parallax corrected'''. There are two buttons above, the finder is certainly set to the closest distance by pushing the larger one. The smaller button slides to the left, certainly to reset the finder to infinity. The extinction meter is offset to the left and has the numbers 1 to 8 visible in a long horizontal window.<REF> Numbers 1 to 8: Baird, p.80 of ''Kuribayashi-Petri Cameras''. </REF> There is a table above, giving a correspondence between the numbers and the speed and aperture values. The name ''B.B. SEMI FIRST'' is engraved above the viewfinder. The front leather is embossed ''Semi First'' in lowercase block letters, as on the standard model. The body edges are in chrome finish, and there is a single red window at the bottom of the back, protected by a horizontally sliding cover.

Advertisements dated March and June 1940<REF> March 1940: advertisement published in {{ACA}}, reproduced in {{Kokusan}}, p.88. June 1940: advertisement published in {{ACA}}, reproduced in Furukawa, p.23 of {{CCN}} no.277. </REF> pictured the camera with a Toko f/3.5 lens and a [[Seikosha (shutter)|Seikosha]] shutter, and mentioned the following features:
* exposure meter;
* parallax compensation device;
* retractible body release, coming in position when the folding bed is extended;
* f/3.5 lens: despite the picture with a Toko, the lens was announced as a Rotte Anastigmat in the March advertisement and no detail was given in June;
* deeper folding bed, allowing the camera to be closed with a filter mounted;
* chrome fittings.
From the pictures observed so far, it is not clear if the retractible body release and deeper folding bed were introduced together with the U Semi First or if they are specific features of the BB Semi First.

Some examples of the metered BB Semi First have '''no parallax correction''' device and have black body edges (instead of chrome). These examples have no marking above the viewfinder.

The metered BB Semi First has been observed in the following versions:
* parallax correction, Toko f/3.5 lens, [[Seikosha (shutter)|Seikosha]] shutter;<REF> Example pictured in Baird, pp.77 and 79 of ''Kuribayashi-Petri Cameras'' and p.73 of ''The Japanese Camera'' (lens no.36787), example pictured in {{MK}}, p.577 and example pictured in [http://www.ajcc.gr.jp/sub1.53.html#semifirst this page of the AJCC]. </REF>

The '''late BB Semi First''' lacks the extinction meter, which was replaced by a [[brilliant finder]].<REF> The model with brilliant finder is called "BB Semi First (Standard)" in Baird, pp.77–80 of ''Kuribayashi-Petri Cameras'', and {{MK}}, p.577, but this designation was not used at the time. </REF> The two finders are grouped in a small L-shaped housing, with the eye-level finder to the left and the waist-level finder to the right. The name ''B.B. Semi First'' is engraved above the eye-level finder. The front leather is still embossed ''Semi First.'' All the examples observed have chrome body edges.

The late 1940 price list cited above mentioned the BB Semi First in five versions: "BB Semi First" (¥121), "BB Semi First II" (¥100), "BB Semi First III" (¥120), "BB Semi First IV" (¥121), "BB Semi First V" (¥160).<REF> {{Kakaku0141_short}}, type 3, sections 4B, 5B, 6B, 7B. </REF> The November 1941 price list does not have the plain "BB Semi First".<REF> {{Kakaku1141_short}}, type 3, sections 4B, 5B, 6B, 7B. </REF>

The production of the Semi First with tubular finder was resumed shortly after the war. The camera was renamed '''Kuri''' and was no longer distributed by [[Minagawa]]. It was certainly made out of spare parts stocked during the war. The word "Kuri" is the first part of "Kuribayashi" (栗林) and means "chestnut". It is embossed in capital letters (''KURI'') in the front leather. The back leather has a ''KURIBAYASHI'' logo in the middle and ''Made in Japan'' on the right. The advance knob is covered by a round piece of leather, unlike the previous models.

All the Kuri cameras observed so far have a First Model-I shutter.<REF> Example pictured in Baird, p.113 of ''Kuribayashi-Petri Cameras'', and in {{MK}}, p.578, example pictured in this page and examples observed in online auctions. </REF> It gives T, B, 150–5 speeds on the early examples and T, B, 200–5 on later ones. This change perhaps indicates that the shutter production was resumed.

The lens is a Kuri Anastigmat 7.5cm f/3.5. Its name certainly indicates that it was produced by [[Petri|Kuribayashi]] itself. It was certainly one of the first camera lenses made by the company, and its production perhaps began during the war. (An example of the [[Auto Semi First]] is known with an S.&nbsp;Kuri Anastigmat 7.5cm f/3.5, perhaps differing in design and probably made during the war.)

Most lens numbers observed have four digits, ranging from 1032 to 3873. The early lenses are engraved ''Kurī Anastigmat'' in lowercase with a macron.<REF> Lens numbers ranging from 1032 to 3002. </REF> Intermediate lenses are engraved ''Kuri Anastigmat'' with no macron; they are mounted on shutters giving either 1/150 or 1/200 top speed.<REF> Example pictured on this page and examples observed in online auctions, lens no.3536, 3787 and 3873. Lens no.3787 is mounted on a 1/150 shutter, the other two on 1/200 shutters. </REF> One presumably late lens is known with ''KURI ANASTIGMAT'' in uppercase letters and five-digit number 46818, where the first two digits perhaps indicate the year of production.

Three variations are known in the finder units. The earliest example observed of the Kuri has an all-black viewfinder with no parallax correction.<REF> Example observed in an online auction, lens no.1032. </REF> Intermediate examples have a mixed assembly with a silver tubular part and a black base, again with no parallax correction.<REF> Examples observed in online auctions, lens no.1407 and 3002. </REF> Later examples have an all chrome unit with parallax compensation, as the one mounted on the wartime Semi First. The parallax correction device is driven by a small sliding button with ''I–N'' markings, surely for <U>I</U>nfinity and <U>N</U>ear.<REF> Example pictured in this page and examples observed in online auctions, lens no.3335, 3536, 3787, 3873 and 46818. </REF>

=== Postwar continuation: the Lorbi ===
The '''Lo Ruby''' is mentioned by Baird and {{MK}} as a renamed version of the Kuri.<REF> Baird, p.115 of ''Kuribayashi-Petri Cameras'', {{MK}}, p.578. </REF> 
The body of the camera shows '''Lorbi''', so '''Lo Ruby''' is a mistranslation of Japanese word '''ロルビー'''. Lens no.47039 may be shown it was manufactured in 1947.
