Konica III 35mm Rangefinder Camera. It works well enough to take pictures. The film advance goes down but does not spring back up automatically. You have to lift it back up with your finger. When you do this, it does advance the film properly. There may be a disconnected spring. Everything else seems to work. The shutter and the lens are fine. 48mm f2 lens.
As it is now, the camera will function and take pictures, but you have to lift the film advance manually. With minor repair work, it should function normally. If you don't mind the inconvenience of lifting the film advance, this is still a usable camera, and faster to use than one with a knob advance.
