This camera is an early model of the Ami-Flex twin-lens reflex camera, released in 1953 by Kanto Optical Co., Ltd. Both lenses are Ami Anastigmat 1:3.5 F=80mm, and the shutter is an NKS B, 1-1/200 second, made by Nippon Kosokki Seisakusho (later known as Talon). The viewfinder is a waist-level finder with a magnifying glass, and there is no sports finder. By the way, in the later models, the shutter was changed from NKS to NKS-TB, and a sports finder was added. Also, a circular or hexagonal "AMI" logo is attached to the center of the lid. The operation is good. Both lenses have some cloudiness. Actual shooting is possible, but the contrast may be slightly reduced. The shutter is working properly. The body has quite a few scratches and dirt. The leatherette has some peeling, but it remains well for its age. The mirror in the viewfinder was quite cloudy, so I cut out and replaced the surface mirror, but it's a amateur job. The viewfinder has become quite bright, but the viewfinder of a twin-lens reflex camera is not that bright even when new. The claw that holds the viewfinder lid is slightly tilted to the right, but this is because the hole on the lid side that receives the claw is shifted to the right, and it is intentionally shifted to the left and right to compensate for manufacturing errors. Kanto Optical was a so-called "four-and-a-half-mat" manufacturer, so they didn't seem to be very particular about manufacturing quality. Overall, it's at a level that can somehow be used for actual shooting. I think this camera has more value as a material for knowing the history of cameras than as a tool for photography.
