This is a camera I found at my parents' house. I think I used it a long time ago, but I'm a complete novice, so I don't know the name or details of the camera. It hasn't been overhauled in decades. Three of the clasps on the case lid are missing (photos 8, 9). The movement seems smooth (in my amateur opinion). Please consider the above points before making a decision. #kenko #OMSYSTEM #135mm
