I haven't shot much B&W 35mm lately, but loaded up the Nikon today and used up some film that's been rebuking me from the back of the fridge. Among the odds and ends that came with my enlarger last year, were a number of Nikkor (or Nikkor-type) tanks and reels. I set everything out on my tabletop and turned out the lights. Wound on the film, got to the end of the reel and had enough extra to go around the reel another full turn. Hmm, must have jumped a groove or 2 early on. Unwound and rewound, but still ended up with 7 or 8 inches too much film. Had a lot of fun fumbling in the dark for another reel, (should have put the film loose in the tank and turned on the lights, but didn't think of that 'til after). Eventually got film wound on another reel, where it fit fine. It must be a reel that came as an extra last year. I've always shot rolls of 36and they've always fitted. Did somebody, at some point, make reels specifically for the shorter rolls of 24? Anybody want one?
