Excuse me if this is either posted before or just common knowledge, but I thought I might post this quick little hack here that enables your FED-1 & Zorki-1 to use Leitz FILCA cartridges, which seem to be a lot more abundant over here than originals...

Only thing is you need to unlock the cartridge by hand. I may work on that later, but I'd need to borrow an original Leica base plate to measure the prong that unlocks the spring on the FILCA. Unlocking a FILCA by hand isn't a problem though, even if it's in place, and bottom loading is 'complicated' anyway, so for now this is going to be it.
