The Tsubasa Spring is a vertical folder, with incurved folding struts. It has a small top housing on the top plate, supporting an accessory shoe and containing the viewfinder. There are two lines in the viewfinder to indicate the field of view for 3×4cm exposures. There is a large button on the right to release the folding bed and a smaller shutter release on the left. The advance key is at the bottom right and the back is hinged to the left. The front leather is embossed TSUBASA.
The lens is a Lucomar Anastigmat 75/4.5. The shutter is a Tsubasa with T, B, 25–100 speeds and a body release. The shutter plate is marked TSUBASA SHUTTER at the top and NEW GOLD at the bottom with a NE logo on the right.
In the various advertising pictures, the lens rim is thin and no focusing control is apparent. However the only pictures of a surviving example observed so far show a front-cell focusing lens.
Advertisements and original documents Edit
The camera was advertised in a variety of names: "Tsubasa Spring A", "Tsubasa Spring", "Tsubasa Spring Camera", "Tsubasa A Chrome", "Tsubasa A Spring". Despite the successive names, no change is visible in the features or in the advertising pictures.
The camera was first advertised in early 1938 as the "Tsubasa Spring A" (ツバサスプリングA), and it was featured as such in the new products column of the June 1938 issue of Asahi Camera. In the June 1938 advertisement in Asahi Camera, the camera is listed as the "Tsubasa Spring" (ツバサスプリング), priced at ¥34. It is pictured with a Tsubasa accessory rangefinder, offered separately for ¥14. In advertisements dated September 1938 and February 1939, the model is called "Tsubasa Spring Camera" (ツバサ・スプリング・カメラ) and priced the same, and the price of the rangefinder is now ¥15. In an advertisement dated April 1939, the camera is called "Tsubasa A Chrome" (ツバサＡ型クローム) and priced at ¥38, and the rangefinder is at ¥16. In a December 1939 advertisement, the name is "Tsubasa A Spring" (ツバサAスプリング), the price of the camera is the same and the rangefinder is no longer mentioned.
The camera appears in the list of set prices compiled in October 1940 and published in January 1941, under the name "Tsubasa Spring B" (¥45), with no further detail.
