Semi Mihama
The Semi Mihama is a Japanese 4.5×6 folding camera, produced by Mihama (or Suruga) during the 1950s. There were at least two models, of which one had variations. All are vertical folders, with no rangefinder, controlling film advance via a red window on the back, and having a "Mihama Anastigmat" 75mm f/3.5 lens. (Mihama does not seem to have been a lens maker, and "Mihama" lenses can be presumed to have been a mere matter of branding.)
An advertisement in the May 1952 issue of the Japanese magazine Camera Fan by Mihama Seikō (三浜精工株式会社) shows the Semi Mihama as a cheaper alternative to the Mihama Six. It has a flat top, from which knobs and a rectangular viewfinder protrude. Surprisingly, three versions are advertised, each with a different shutter: "I", MHS shutter (B, 25–150); "II", MHS shutter (yes, the same name; B, 10–200); "III", NKS shutter (B, 1–200, with self timer).
An advertisement in the January 1955 issue of the Japanese magazine Shashin Salon by Mihama's successor Suruga Seiki (駿河精機株式会社) shows a different-looking Semi Mihama, with a more rounded top. This has an NKS shutter (B, 1–200, with self timer); it is not referred to as "III" or anything else beyond simply "Semi Mihama".
