My c33 has a 220 adapter thing on it. It lets me shoot past 12, until 24. I usually just crank through until the film gets to 24 and i'm sure it's all on the reel. At 13 I took this photo, not sure if it would come out. It clipped the top of the image but I love it anyway.
BUT. I scored some free 220 (expired) film off Craigslist yesterday and I'll get to put the 220 conversion to use. YAY.
I also clipped it too hard when i was hanging to dry and had to heal a few scratches in PS. I've rigged my own hanging thing with binder clips and the shower curtain ring.
