The Tsubasa Chrome is a Japanese camera taking 4×6.5cm and 3×4cm exposures on 127 film. It was sold by the Japanese company Optochrom from 1937.

General description

All the models have a telescopic tube supporting the lens and shutter assembly. They have a tubular optical finder in the middle of the top plate, with two bars indicating the field of view for 3×4 format. The advance knob is at the left end and the release lever is on the shutter housing itself. The back is hinged to the right and film advance is controlled by red window. The front leather is embossed TSUBASA.

Original model

The original Tsubasa Chrome (ツバサ・クローム) has T, B, 25, 50, 100 speeds. The advance knob has a cylindrical shape and their is a smaller cylindrical knob at the opposite end of the top plate. There is a button on the right of the top plate, looking like a body release. Actually it is probably the release of the spring loaded telescopic tube. The back contains two uncovered red windows.

The shutter plate is marked TSUBASA SHUTTER at the top, with a NE logo between both words, and NEW GOLD at the bottom. The speeds are written on the shutter plate itself and they are selected by turning a very thin rim. The aperture scale is at the bottom.

The camera was featured in the new products column of the August 1937 issue of Asahi Camera.[1] An advertisement dated August 1937[2] offered the model with a Lucomar f/6.3 lens (¥19.50) or a Lucomar f/4.5 lens (¥28.50) — case cost extra ¥4. In an advertisement dated June 1938,[3] the prices were respectively ¥23 and ¥34 (case for ¥4.50).

Three examples have been observed.[4] Their advance knob is smaller and higher than on the advertising pictures and it has three rows of knurls. Two of them have a Lucomar Anastigmat f/6.3 fixed-focus lens and speeds marked T, B, 25, 50, 100 in that order. The aperture scale has 6.3, 8, 11, 16, 22 settings. The shutter plate has a single metal strip on each side of the lens and the NEW GOLD name is written in rounded letters. The third one has a Lucomar Anastigmat f/4.5 front-cell focusing lens and speeds marked T, B, 100, 50, 25. The aperture scale has 4.5, 6.3, 9, 12.5, 18, 25 settings. The shutter plate has three metal strips on each side of the lens and the NEW GOLD name is written in square letters.

Tsubasa Chrome New

The Tsubasa Chrome New (ツバサ・クローム・新型) adds 1/150 top speed. The advance knob has a more rounded shape and a hollow top, and the small knob at the right end of the top plate has a conical shape.

The shutter plate is marked WING ANCHOR at the top, MADE IN JAPAN at the bottom, and the NE logo is on the right. The speeds are engraved T, B, 150, 100, 50, 25 in that order in the shutter rim. There is a distant release connector added next to the release lever.

An advertisement dated September 1938[5] offered the camera with the Lucomar f/6.3 lens (¥25) or the Lucomar f/4.5 lens (¥34, case ¥5 extra). In the advertising picture, the new shutter plate is of the new type and there is still a button on the right of the top plate.

This button is no more visible in the picture of an advertisement dated February 1939, which offered the camera at unchanged prices.[6] The disappearance of the button probably means that the telescopic tube was no longer spring-loaded.

The camera was simply called Tsubasa Chrome again in an advertisement dated April 1939,[7] where the price of the f/6.3 variant had raised to ¥28. Kokusan kamera no rekishi does not mention any advertisement posterior to 1939. The Tsubasa Chrome is mentioned in the list of set prices compiled in October 1940, under the names "Tsubasa Chrome" (¥28), "Tsubasa Chrome II" (¥33) and "Tsubasa Chrome IIA" (¥42), with no further detail.[8] A Japanese catalogue reportedly dated 1942 lists the Tsubasa Chrome with Lucomar f/6.3 only, for ¥40 — case ¥6.70 extra.[9]

Actual examples of the Tsubasa Chrome New have been observed on various occasions, with or without the telescopic tube release.[10] There are variations in the shape of the film flange at the top right. All the examples observed so far have a fixed-focus f/6.3 lens.

Later version

A single example of a probably later version has been observed.[11] It has a big key in place of the advance knob. The back latch is different and consists of a long sliding bar. The back has a round metal plate in the middle and a single red window on the right. This does not necessarily mean that the dual-format capability was dropped, and the viewfinder still has the two bars for 3×4cm pictures. (It seems that at least some of the 127 film rolls sold in Japan at the time had indications for half-frame pictures on the paper backing.) There is an accessory shoe (perhaps not original) to the right of the viewfinder, in place of the telescopic tube release of the early version.

Notes

  1. Kokusan kamera no rekishi, p. 337.
  2. Advertisement published in Asahi Camera, reproduced in Kokusan kamera no rekishi, p. 78.
  3. Advertisement published in Asahi Camera, reproduced in Kokusan kamera no rekishi, p. 78. Eight authorized dealers are mentioned: Asanuma Shōkai, Hagi Kōgyō Bōeki, Misuzu Shōkai, Mizuno Shashinki-ten, Yamashita Yūjirō Shōten, Eikōdō, Matsuzaki Shashinki-ten and Ueda Shashinki-ten.
  4. Examples observed in online auctions.
  5. Advertisement for the Tsubasa range published in Asahi Camera, reproduced in the Gochamaze website.
  6. Advertisement published in Asahi Camera, reproduced in Kokusan kamera no rekishi, p. 78. It is looking the same as the September 1938 advertisement cited above, but there are detail differences.
  7. Advertisement published in Asahi Camera, reproduced in Kokusan kamera no rekishi, p. 79.
  8. Template:Kakaku1940 short, type 1, section 3 and type 2, sections 3 and 5A.
  9. Scans observed in an online auction.
  10. Compare e.g. the examples pictured in Sugiyama: item 4102 with the tube release and item 4099 without. Item 4102 has a folding frame finder which does not look original, and it is simply called "Tsubasa" by mistake.
  11. Example observed in an online auction.
