I took my Fed 3b to my son's wrestling tournament (what a weird scene that is), unsure how many pics I had left on the roll, and didn't have a fresh roll with me (remember the old days when somebody always had an extra roll of film 😡) so it turned out I only had two shots left...fine...then I went to rewind, and was pre-occupied, kids all around me, and my knob must be stripped or something 'cause I wound for about two minutes, sometimes getting resistance sometimes not. Finally I opened up the back, and there is the loaded film staring me in the face. Most of the roll was ruined, lots of great snow pics lost. But the first few shots survived, albeit with a bit of flare (they are the "green ball" and the orange-coated child shots in my gallery). I don't know what's up with the Fed though... 🙁
