Seikosha (shutter)
The Seikosha is a Japanese leaf shutter made by Seikōsha, the manufacturing branch of Hattori Tokei-ten, in the late 1930s and early 1940s. It was inspired by the German Compur and was released around 1935.[1] It was called "S Seiko" (Sセイコー) in some advertisements.[2]
It only exists in #0 size, its range of speeds is T, B, 1, 2, 5, 10, 25, 50, 100, 250 and it has a self-timer.

Notes
- ↑ Date: the Seikosha is listed in an advertisement for the First, Special First and First Roll dated September 1935, reproduced in Kokusan kamera no rekishi, p.85. Lewis says 1935 on p.46. Baird says 1936 on pp.15 and 18 of Kuribayashi-Petri Cameras, but this is at least one year too late. Shunkan o torae-tsuzukeru shattā-ten, p.9, and the corresponding exhibition page say 1932, but this seems implausible.
