Alright 67II users, I need some input. A few weeks ago while hiking/camping, the film advance lever on my 67 TWICE locked up mid-roll. It wouldn't budge after firing off a frame to allow me to advance to the next frame. I decided to sacrifice the roll I had just loaded — only two exposures in — and open up the back. I pulled out the film, released the film spool holders and tried again. Still nothing. But after about a minute of jiggling the film advance back and forth it reluctantly advanced, fired, then was back to normal for the whole day. The same thing happened again the next day. Four frames in, fired one off, tried to advance. Locked up. I tried jiggling the advance lever again and it didn't work, so i just threw the camera in my bag and walked on. After some Googling, this seems to be a pretty common problem with this camera.
Anyone have this issue or heard of it? From what I've read, people are saying to advance slowly each time and stop at the end of the advance for a second or two, then return to the start position. I'm really hoping this is not a recurring problem because it was totally of the blue, and I'm just glad I wasn't shooting client work when it happened.
