Anyway, Bring your camera down for an initial accessment. It might not be advisable to fix some cameras as everything have a lifespan and parts availability. Unless somethings have sentimental value, sometimes it might not be worthwhile to fix it, better to get another better copy.
Pentacon parts are near non-existance today. If you are referring to the winding mechanism, then good luck, you can never find parts unless you do a physical transplant. :bsmilie:
