The '''original Waltax''' (ワルタックス) has a folding optical finder, the film is wound by a key on the bottom right and the tripod screw is on the bottom left. The name ''Waltax'' is embossed in the front leather, and an ''OKAKO TOKYO'' logo is engraved in the folding struts. According to {{Kokusan}}, it is featured in the new products column of the June 1940 issue of ''Asahi Camera''.

In two pages of the AJCC website{{ref|2}}, there is a mention of a camera attributed to Okada Kōgaku, dated 1940 and confusively called both '''Semi 2600''' and Waltax. The year 1940 is the year 2600 of the Japanese imperial calendar that was sometimes used in military ruled Japan, this might explain the name. In the picture provided, the camera is presented with original documents. The camera itself looks similar to the original Waltax. One of the documents is written Waltax and displays a picture from the back, showing two red windows at the top of the back, protected by a common sliding cover.

The original Waltax is also offered in wartime advertisements{{ref|1}} for &yen;185 (a case is sometimes offered for an extra &yen;7.70). In one of them, the maker is stated as Okakō (岡光, an abbreviation of Okada Kōgaku). The distributors are [[Nihon Shōkai]] and the wholesale branch of Honjō Shōkai (本庄商会卸部). When mentioned, the lens is a four element Tessar-type Kolex Anastigmat 7cm f:3.5, and the shutter is a Dabit-Super with T, B, 1&ndash;500 speeds and a body release. {{Kokusan}} says that some advertisements mention an f:2.8 lens, but does not show any. At the same time, Okada Kōgaku was also making the [[Semi Okaco]], a very similar camera distributed by Kawara Shashinki-ten and offered with a choice of f:2.8, f:3.5 and f:4.5 lenses.

The Waltax is a series of Japanese 4.5×6 folders, whose body is copied from the Ikonta A. The prewar and wartime original Waltax was made by Okada Kōgaku and distributed by Nihon Shōkai. Both Kokusan kamera no rekishi and McKeown attribute the postwar Waltax cameras to Daiichi Kōgaku, but this is unlikely, as we will see. The Zenobia series of folders by Daiichi is indeed very similar to the late Waltax models.

The original Waltax

Prewar and wartime

The original Waltax (ワルタックス) has a folding optical finder, the film is wound by a key on the bottom right and the tripod screw is on the bottom left. The name Waltax is embossed in the front leather, and an OKAKO TOKYO logo is engraved in the folding struts. According to Kokusan kamera no rekishi, it is featured in the new products column of the June 1940 issue of Asahi Camera.

In two pages of the AJCC website[1], there is a mention of a camera attributed to Okada Kōgaku, dated 1940 and confusively called both Semi 2600 and Waltax. The year 1940 is the year 2600 of the Japanese imperial calendar that was sometimes used in military ruled Japan, this might explain the name. In the picture provided, the camera is presented with original documents. The camera itself looks similar to the original Waltax. One of the documents is written Waltax and displays a picture from the back, showing two red windows at the top of the back, protected by a common sliding cover.

The original Waltax is also offered in wartime advertisements[2] for ¥185 (a case is sometimes offered for an extra ¥7.70). In one of them, the maker is stated as Okakō (岡光, an abbreviation of Okada Kōgaku). The distributors are Nihon Shōkai and the wholesale branch of Honjō Shōkai (本庄商会卸部). When mentioned, the lens is a four element Tessar-type Kolex Anastigmat 7cm f:3.5, and the shutter is a Dabit-Super with T, B, 1–500 speeds and a body release. Kokusan kamera no rekishi says that some advertisements mention an f:2.8 lens, but does not show any. At the same time, Okada Kōgaku was also making the Semi Okaco, a very similar camera distributed by Kawara Shashinki-ten and offered with a choice of f:2.8, f:3.5 and f:4.5 lenses.

The three wartime advertisements observed seem to show the same picture. The shutter plate is written OKAKO TOKYO at the top, the shutter rim is written DABIT–SUPER at the bottom and the aperture is set by an index at the bottom of the shutter housing.

The examples observed are slightly different: the aperture index is on the top of the shutter housing, and the DABIT–SUPER marking is at the bottom of the shutter plate instead of the speed setting rim. Some have a depth of field knob on the top right of the body, see this post at a Chinese forum (lens No 13895) or the picture in McKeown under the Okada entry (lens No 1402x). A later one has been observed with no depth of field knob at an eBay auction (lens No 17082). On this example the back has only one red window at the bottom, protected by a sliding cover.

Postwar

The original Waltax is still advertised in 1947[3]. The camera pictured is the same with a depth of field knob now on the body's top left. The lens is still a Kolex (No 180xx). The focal length is barely legible on the lens bezel, but it could be 7.5cm. The camera is distributed by Tōyō Shashinki-zai K.K.[4] (東洋寫眞機材株式會社, in old writing), and there is no mention of Okada. Another example with no depth of field knob is reported with a Kolex 7.5cm f:3.5 (No 19006)[5].

Kokusan kamera no rekishi and McKeown both attribute the postwar Waltax, as well as all the following models, to Daiichi Kōgaku, but no original document has been observed yet to sustain this. On the contrary, all the models observed have Okako logos: see the descriptions below.

The Waltax II and III

From now on, all the Waltax models have a finder enclosed in a top housing, an accessory shoe and an advance knob on the top left. The red window, protected by a sliding cover, is now at the back's top because the film is running from right to left. The tripod screw is centered and there are two decorative knobs at both ends of the bottom plate.

Advertisements

The Waltax II (ワルタックスⅡ型) is advertised at least in 1947[6] by the distributor Tōyō Shashinki-zai. There is a depth-of-field knob on the top right and a logo above the top housing in front of the accessory shoe. The advance knob looks a little smaller than on the later models, and a small hole is visible besides, probably a double exposure prevention indicator. The advertisement observed mentions auto-stop film advance but there is no exposure counter and this feature is maybe confused with the double exposure prevention.

The Waltax III (ワルタックスⅢ型) is advertised at least in 1949[7] by the same distributor. The advertisement mentions flash synchronization and double exposure prevention. According to Kokusan kamera no rekishi, these two features distinguish the III from the II, but it is highly unlikely that the II has auto-stop advance without double exposure prevention, especially considering the 1947 picture mentioned above. The advertisement for the Waltax III seems to emphasize the flash synchronization: there is a flash synch connector added to the shutter and this portion of the picture is enlarged. This is probably the distinguishing feature between the two models. It seems that the later Waltax Senior is simply a renaming of the Waltax III, see below.

The advertisement for the Waltax III also says that it takes 620 film, the lens is mentioned as a Bio-Kolex f:3.5 and the shutter is called "Dabit Compur" (ダビツトコンパー), surely by mistake. In the camera pictured, the logo has moved to the front of the top housing.

Description of a Waltax II

An example of the Waltax with top housing but no flash synch, probably corresponding to a Waltax II, has been observed at a Yahoo Japan auction.

The lens is a Bio-Kolex Anastigmat 7.5cm f:3.5 (No 22697). The shutter has B, 1–500 speeds and is not synchronized. The shutter plate is black, written OKAKO TOKYO at the top and likely DABIT–SUPER at the bottom (only partly visible).

The top housing has a depth of field knob on the right (engraved in feet in this example), with the folding bed opening button nearside. The advance knob is on the left, it has a striated top and a red arrow engraved in the rim. Very close to it, there is a small hole, certainly for double exposure prevention. The shutter release is also on the same side. The back has one red window, protected by a sliding cover. No exposure counter is visible, and it is unclear if this camera really has auto-stop advance or simply double exposure prevention.

The name Waltax is embossed in the front leather. Unlike the Waltax II pictured in the ad, there is a Waltax OKAKO logo engraved in front of the top housing, and the serial number (No 21277) is engraved above the top housing in front of the accessory shoe. There is an OKAKO TOKYO logo engraved in the body struts. The back leather is missing, but on later models it is embossed with the same logo.

The viewfinder front trim is very thin, separate from the top housing. The standing leg has a squarish shape. These two characteristics are shared by the cameras pictured in the 1947 and 1949 advertisements mentioned above. All the later examples observed have a thicker finder trim, part of the top housing, and a standing leg with a more pointed shape.

From the Junior to the Acme

The Waltax Junior

The Waltax Junior (ワルタックスジュニア) is a cheaper model. The film advance is controlled by a red window in the back, protected by a sliding cover, and there is no film advance indicator. The lens is a Bio-Kolex Anastigmat 7.5cm f:4.5 and the shutter is an Okako with B, 25–150 speeds. The depth of field knob is replaced by a Waltax Junior engraving on the right of the top housing.

The serial number is engraved above the top housing in front of the accessory shoe. The Waltax OKAKO logo has disappeared from the top housing, but there is an OKAKO TOKYO logo embossed in the back leather and the shutter plate is marked OKAKO in big letters at the bottom. In view of all these Okako markings, the attribution to Daiichi Kōgaku is dubious.

The Waltax Junior seems to be the most common version of the Waltax. According to Kokusan kamera no rekishi, it appears in magazines from 1950 to 1952.

Two versions have been observed, and a chronological classification can be attempted based on the serial numbers and other logical considerations.

The early version has straight body struts, different from all the other Waltax models (illustrated for example in McKeown). The earliest ones have an unsynched shutter and the striated advance knob described on the Waltax II. On later ones, the advance knob is substituted by a newer model, with a red arrow engraved inside a shallow depression on the top, and the shutter is synchronized with an ASA bayonet connector on the top right.

The late version returns to the same body struts as the other Waltax models, engraved with an OKAKO TOKYO logo. It was probably better for the company to have the same standard body for the whole range than to have a special cheaper body for the Junior model.

The Waltax Senior and Deluxe

The Waltax Senior (ワルタックスシニア) is probably the new name of the Waltax III, and all the features are similar. According to Kokusan kamera no rekishi, the Waltax Deluxe (ワルタックスデラックス) is the same camera with an added selftimer, and both appear in 1951 and 1952 magazines, together with the Waltax Acme (see below).

A number of Waltax cameras have been observed with flash synchronization and a top housing slightly different from the Waltax II described above. They are assumed to be examples of the Waltax Senior or late Waltax III. No example of the Waltax Deluxe has been observed yet.

They have a thick viewfinder trim, part of the top housing. The advance knob is of the newer type, with a shallow depression, and the hole for the film advance indicator is more distant from the knob than on the Waltax II. The standing leg is also different from the one on the Waltax II, with a more pointed shape. The lens marking has a red C. between Bio-Kolex and Anastigmat, probably indicating a coated lens. The shutter is synchronized, with an ASA bayonet connector on the top left.

The Waltax name is absent from the front leather, but all the other logos are present: Waltax OKAKO in front of the top housing, OKAKO TOKYO in the struts and in the back leather. Some examples have a MADE IN OCCUPIED JAPAN marking embossed in a small piece of leather on the back opening.

The early variant[8] has a black shutter plate written OKAKO TOKYO at the top and DABIT–SUPER at the bottom. The late variant[9] has a white unmarked shutter plate, with D.O.C.–RAPID engraved in the shutter rim. No other difference is visible, the shutter characteristics and the other markings are the same. A Waltax Junior has also been reported by a dealer as having a DOC-Rapid shutter. "D.O.C." is plausibly an acronym of Daiichi Optical Company, a translation of Daiichi Kōgaku K.K. The Zenobia folders are maybe the follow-ups of the Waltax model, after Okada either changed its name or was bought by Daiichi.

The Waltax Acme

The Waltax Acme (ワルタックスアクメ) is a rangefinder version of the Waltax Senior. The coupled rangefinder, separate from the viewfinder and enclosed in the top housing, is inspired by the Super Ikonta: a pivoting arm mounted on the shutter housing supports a rotating lens in front of one of the two round rangefinder windows. According to Kokusan kamera no rekishi, the other characteristics are the same as the Waltax III or Senior, and it appears in 1951 and 1952 magazines.
