The Prince Flex looks somewhat like the first [[Ikoflex]] "coffee can" model, with a hexagonal front standard. The focusing is done by moving this front standard back and forth. Some sources say that it is controlled by a lever driving a helicoid;<REF> See {{Kokusan}}, p.12 and [http://www.geocities.jp/yume_camera/princeflex.html this page at yume_camera]. </REF> however the pictures show no focusing lever but a knob placed on the photographer's left. (The mention of a lever and helicoid is perhaps a confusion with the Ikoflex which has such a lever underneath the front standard.) The film advance is driven by a knob on the right and controlled by red window.

There is a X-shaped rib on the viewing hood, with a small plate at the centre, inscribed ''Prince Flex.'' There is another nameplate engraved ''Neumann & Heilemann'' at the top of the front plate. The serial number is written above the viewing lens, again on a small plate attached by two screws.

This is a work in progress.

The Prince Flex is a Japanese 6×6 TLR, made by Neumann & Heilemann, then by Fujimoto Shashinki Seisakusho and distributed by Fukada Shōkai from 1937 to 1939.

This camera has no design feature in common with the Princeflex camera made by Tōyō Seiki Kōgaku, then Cosmo Camera in the 1950s. (See the Prince page for a discussion of the various cameras with that name.)

Maker

The Prince Flex was developed by the company Neumann & Heilemann in 1937, perhaps from an order by the distributor Fukada Shōkai. It is said that the body casting was bought to a sub-contractor, and that the assembly took place in the Takagi plant.[1] This is the origin of the Neumann & Heilemann marking visible on the camera. The company reportedly had much difficulty to cut the focusing helices and to properly assemble the camera, and at least part of the process was finally transferred elsewhere.[2]

The company Neumann & Heilemann was absorbed in September 1937 by Fujimoto Shashinki Seisakusho, and the Takagi plant became Fujimoto's Mukogawa plant.[3] (Fujimoto was the maker of the Semi Prince folder, which was distributed by Fukada too.) The production of the former Neumann & Heilemann products (including the Prince Flex) continued undisturbed, and the former company name and NH logo were retained in the markings.

All the advertisements seen so far were placed by the distributor Fukada Shōkai.[4] Some of them have a stylized P.C.W. logo, standing for "Prince Camera Works", a dummy name used by Fukada for advertising purpose (see Fukada and Camera Works).[5] None mentions the manufacturer Neumann & Heilemann or Fujimoto.

The new products column in Asahi Camera September 1937 attributes the camera to Fukada Shōkai, and an article in the November 1937 issue of the same magazine says that the camera was "the first product released to commemorate the merge of Neumann & Heilemann with the Prince camera factory", actually corresponding to the Fujimoto company.[6]

First Japanese 6×6 TLR

The Prince Flex was the first Japanese 6×6 TLR, announced in summer 1937, before the Minoltaflex (December). The first advertisement appeared in Asahi Camera in August, and the camera was featured in the new products column of the same magazine in September.[7] (One source says that the camera was released in July, but no original document has been found to confirm this.)[8] It is said that the announce of the camera was precipitated by the news that the Minoltaflex would be released soon.[9] It seems that the camera was not really ready for production, hence the problems met by the company.

A year previously, the 4.5×6 Hansa Rollette Ref had been the first TLR-shaped Japanese camera, but the viewing lens was not used for focusing.[10] The 4.5×6 Roll Light Ref was released in January 1937 but it is not entirely clear if it is a real TLR or a pseudo TLR.[11]

Advertisements and other documents

The earliest advertisement, in the August 1937 issue of Asahi Camera, gives the price of ¥165.[12] The new products column of the following month's issue repeats the same price, and mentions 1/200 top speed, perhaps by mistake.[13] The advertisement published in the same September issue gives no price, and offers the camera along with the Semi Prince II.[14] Advertisements published in Asahi Camera November 1937, February and July 1938, and January 1939, give the price of ¥198.[15] According to Awano, the sudden price rise between August and November 1937 was caused by the introduction of a new 20 percent excise tax after the outbreak of war with China.[16]

The last reported advertisement for the Prince Flex is dated April 1939.[17] It seems that the contract between the manufacturer Fujimoto and the distributor Fukada was rescinded in late 1939 or early 1940; the Semi Prince was then transformed into the Semi Sport,[18] and the Prince Flex was certainly completely abandoned at the time. The camera is not in the official list of set prices compiled in October 1940 and published in January 1941, presumably because it was no longer sold.[19]

Description

The Prince Flex looks somewhat like the first Ikoflex "coffee can" model, with a hexagonal front standard. The viewing and taking lenses are mounted on two helices geared together, moving this front standard back and forth.[20] These helices are driven either by a lever or by a knob on the photographer's left (see the evolution below).

The film is advanced by a knob on the photographer's right. The advance is controlled either by an exposure counter on the back or by a red window (see the evolution below). The camera can take either 120 film or 620 film, a feature which was certainly unusual in Japan at the time.[21]

The viewing hood perhaps contains a removable magnifying lens.[22] It has an X-shaped rib at the front, with a small nameplate at the centre, inscribed Prince Flex. There is another nameplate engraved Neumann & Heilemann, attached to the top of the front plate. The serial number is inscribed on a small plate attached to the hexagonal front standard, above the viewing lens.

The taking lens is a four-element Neotar 7.5cm f/4.5 and the viewing lens is a Radionar 7.5cm f/3.5, certainly with three elements.[23] Both lenses are engraved Neumann & Heilemann, and only the Neotar has a serial number. These lenses were specifically made for the Prince Flex. They were certainly assembled by the Neumann & Heilemann factory from imported elements supplied by Schneider.[24] This ambiguous situation probably explains why the article in Asahi Camera November 1937 says that the lenses were "made in Japan", whereas advertisements in the February and July 1938 issues of the same magazine mentions the Neotar as a "luxury four-element German lens".[25]

The shutter is a Perfekt by Neumann & Heilemann, with a setting lever at the bottom and a release lever at the top. The shutter plate is inscribed NEUMANN & HEILEMANN or NEUMANN HEILEMANN at the top and PERFEKT at the bottom, and has an NH logo on the right. It either has a single silver stripe or two silver stripes on each side of the lens. This shutter was specially made for the Prince Flex, and was called "New Perfekt" (新パフェクト) in the original documents. All the known surviving examples have 1–300, B, T speeds. The new products column of the September 1937 issue of Asahi Camera mentions 1/200 top speed, perhaps by mistake, and the article in the November 1937 issue of the same magazine says 1–300, B, T.[26] The "New Perfekt" was announced as patterned after the Compur, and was optimistically advertised as having the same features as the Compur-Rapid.[27]

Actual examples

To be reworked.

The actual examples slightly differ by the presence or absence of a lever placed to the side of the hexagonal front standard, on the photographer's left.

The only serial numbers observed so far are 614 and 768.[28]
