<p>The film reached its end during the middle of my moving the film advance lever. Film is out now. Lever has never finished the aborted rotation that started the problem. In its current condition the mirror is up although I can move it down and then see through the viewfinder. When I do that I can actually feel a click when I push the shutter release button, but the shutter blind never moves, although the mirror goes back up.. I have tried loading a new roll, etc. but nothing unsticks the film advance lever. Because it happened because the film ran out I am optimistic that there is a simple solution, but it has certainly escaped me!</p>
