This is a PrimoFlex twin-lens reflex camera released by Tokyo Kogaku (Topcon). It was a representative model of Japanese twin-lens reflex cameras. It features a smooth film advance mechanism using a magatama-shaped cam. The shutter is charged manually, and the exposure system is simple. Although it's a camera from nearly 70 years ago, the shutter, film advance, and other functions still work perfectly, allowing for shooting today. However, the infinity focus on this camera is slightly off. It's currently being adjusted. *Adjustments and maintenance performed: Body: Sterilization cleaning. The body is clean for its age. There are some areas where the leatherette is peeling. Lens: Disassembly and cleaning. It's clean. Focus: The infinity focus is slightly off. It's currently being adjusted. Viewfinder: Disassembly and cleaning. The view is now clear. Film chamber: Clean. (Test Shooting) I tested it by attaching ISO100 Seagull 35mm film to the back plate with tape. I took another test shot. 1/100 F8. This time, the photos came out well. The focus is soft in the distance. Unfortunately. This is a carefully crafted camera. *Negative Service After the adjustments and maintenance are complete, I will take test shots and check them. I will provide the negatives from those test shots to anyone who wants them. This is proof that the adjustments and maintenance have been done correctly. *What is included: Camera body. *Specifications Tokyo Kogaku/PRIMOFLEX I Lens: Toko 75mm F3.5 3-element Focus adjustment: Twin-lens reflex, front plate extension Aperture: 3.5-16 Shutter: Rectus (B, 1-1/200) Release: 1952 PrimoFlex
