Don't laugh just because I have the Zenit E, and still love it. It was my first slr. It is in mint condition and I still used it occasionally until recently, when I managed to jam the film advance lever. There was no film in, and I was 'exercising' the shutter and winder. At the time I also had a cable release fitted into the shutter release button, and that was when the problem reared its head. I have seen Tom Tiger's site and tried his remedy, - turning the shutter release button. No success. Tried using the delay timer, but again no success. I have had the bottom plate off and also tried his suggestion re pulling on the black lever. Still no joy. As regards taking off the top plate, I think that may be a bit too advanced for me. Professional repair ? - too costly when compared with prices for a Zenit E on the bay. So if anyone has a quick and simple remedy I would be more than grateful.
