Hi Bill. When you loaded the film, did you wind the film to the 1st frame using the winding handle on the back? Have you tried replacing the darkslide and removing the back? Once you've done that it should be easier to diagnose. Also, you mention that the shutter is cocked, but the lens is closed. Did you prefire the body, which raises the mirror, opens the secondary shutter in the body and closes the shutter in the lens? That's the only action that normally results in what you're seeing. I haven't really got any idea of what's happened, I'm just trying to get some more information. If you could let us know specifics of the gear you're using, and how everything is set, maybe somebody can come up with a solution. Pictures help too.
