I have a Super Speedex in very nice cosmetic condition with one issue. On three frames when shooting (2, 3, and 11), you must hold down the shutter button after taking the shot and wind the film half a turn of the wind knob before releasing the shutter button. Otherwise, the shutter button will lock at that frame preventing any other shots on the roll. Otherwise, the camera is perfect. Clean, clear perfect lens. Syncho-Compur shutter sounds great at all speeds. Smooth focusing/ no binding. Rangefinder is clear and accurate. Everything else is working as it should. So, if your willing to put up with this nuisance, let me know.
