My camera's (Seagull DF 2ETM although I doubt that is necessary), shutter cloth is stuck so that it leaves part of the back plate exposed. The shutter lever is stuck too and so is the shutterbutton. I need serious help.
With a bit of luck you can still find a camera repair place. By all means get an estimate, since it could well cost more than the value of the camera to repair it. It might be best to consider it a "collector's" camera and go shopping - used film cameras are not in high demand, and you may find something really nice at a good price.
