Hi guys, I bought a 35 a few months ago and ran through my first film. Unfortunately I wasn't able to rewind the film and ended up cutting it out. Threads on similar problem suggested to not force the rewind. So today I decided to do a little investigating and playing around with my ruined film to see how exactly the loading/rewinding works. Loading the film is fine. I can see how the loading and film advance works now with the back plate off. However, I'm not able to rewind the film. I've switched the rewind lever upwards, but the spool cannot be rotated in the opposite direction. Is the spool supposed to be able to rotate freely when the rewind lever is in the upward position (with no film loaded/back plate off)? Also, say I shot the last frame (24). Am I supposed to do the rewind with the lens still protruding outwards? Thanks guys!
