Semi Chrome
The Semi Chrome are Japanese 4.5×6 folders that were made by the company Optochrom.
The Semi Chrome A
The Semi Chrome A is a vertical folder, with a key to wind the film. It is unclear if the folding finder is an optical one or a simple frame finder. The only advertisement mentioned by Kokusan kamera no rekishi is dated February 1937[1], and no price is indicated. The shutter has T, B, 5–150 speeds, and it is probably a Rulex: on the picture, the shutter plate is marked Semi Chrome at the top and RULEX at the bottom, with a logo at the right that is probably the NH logo of Neumann & Heilemann. The lens aperture is f:4.5 but the lens name is a bit confusing: it could be New Gold Lausar[2], or New Gold and Lausar could be a choice of two different lenses.
The Semi Chrome B
The Semi Chrome B[3] is a strut folding camera. It is advertised in 1937[4] and 1938[5], at first with a New Gold f:4.5 lens (¥38) and later also with a Lausar[6] f:4.5 lens (¥45) — case ¥5 extra. The shutter has T, B, 25–100 speeds. On the pictures or drawings of the advertisements it is unclear if the folding finder was an optical one or a simple frame finder. The front leather is sometimes embossed SEMI CHROME and sometimes simply CHROME. Sometimes the advance knob seems to be at the top left of the body and sometimes it is at the bottom right.
