This is a tiny Mycro camera first introduced by Akita Seisakusho in 1939 and manufactured into the 1950s by various Japanese companies. This model was likely made in the early 1940s and has no manufacture's mark, indicating it was probably made by Akita Seisakusho.
It takes 10, 14 x 14mm exposures on un-perforated film. The camera is untested but has no significant cosmetic issues. The case is entirely leather and is in excellent condition. The camera without the case is 2" in width, 1 3/8" in height and 1 1/4" front to back. It weighs 2 1/2 oz. Nice teeny tiny bit of nostalgic photography equipment for display, prop or for a back-in-the-day photo taking experience.
