I just got a Canon IIf from my grandpa, who used it a lot for about 20 years, then gave it to my uncle, who lost a couple of it's parts... Luckily, he didn't do any more damage to it; the shutter seems to function very well at all speeds, and the lens is great.

I was able to find a bottom plate on eBay for a fairly good price, but I haven't seen any take up spool. I've been told that early Leica spools will work, but that I should hold out for a Canon spool, which is much nicer. Does anyone know where I might find one?
