Thank you for the picture. I was able to turn the back and it looked like that piece of metal (C) was pushed too far in. It doesn't seem to move freely but I was able to push it out and it then worked. I guess the question is is that pin supposed to move freely like the thin pin that goes into the camera which does move freely or was it just out of position and I had to push it back in? I have film in there but after I finish a roll I'll have to see if the shutter can fire with the darkslide in? (ie. did I disengage an interlock to prevent that by pushing it out. Does "C" move freely on your's??? I know A and B do and should. If it doesn't that maybe a job for lighter fluid? In the meanwhile I should be able to shoot a roll with it tomorrow
