This camera is a 35mm rangefinder camera released in 1955 by Sanei Sangyo Co., Ltd. (renamed Samoca Camera Co., Ltd. from 1955 to 1958, then reverted to the original company name, Sanei Sangyo Co., Ltd.). The difference from the Type II released in 1953 is that the rotating helicoid was changed to a straight helicoid. At that time, Sanei Sangyo did not seem to have the technology to permanently mount the film winding shaft in the camera, so it followed the 120 film winding method and used a dedicated spool instead of a shaft. Also, the shutter charge button also serves as the winding lock release and film counter advance button. This button is also used when rewinding the film. Note that the lock release and counter will not move if there is no film loaded. Operation is good and there are no problems with function or performance. There is a small chip on the lower left of the bakelite part inside the body, but it does not leak light. The camera case with strap is partially damaged, so please consider it as a storage container for the camera. Since it is not equipped with a light meter or rangefinder, there is no need to worry about malfunctions. The lens has some clouding around the rear element, but I don't think it will significantly affect the image quality. The viewfinder is generally clear. The viewfinder eyepiece can be removed by turning it, making it easy to clean the inside of the viewfinder. As an aside, the "AAA" logo displayed on the camera is a pun, replacing the company name "Sanei Sangyo" with "3A Sangyo". *Specifications* Type: Rangefinder camera Manufacturer: Sanei Sangyo Co., Ltd.
