ZEISS IKON Super Ikonta 531 camera with rangefinder for 120 film #2439*
Device in good condition. The spring to extend the lens is tired. You have to pull on the door to open it. Contrasting and functional rangefinder. Smooth focusing. Selection of speeds and diaphragm OK. Be careful, you must advance the film and cock the lens before you can trigger. The lens is foggy and requires cleaning. Some cleaning micro-abrasions, no fungus, no peeling. Overall functional.
