[Leica] Re: Leica M-3 all or nothing

That's a lesson I learned too, but I still don't roll it all the way  
back in- I fold the tip, or if the film is brittle enough (I'm  
thinkin' "Super Kmart Special") I break off the leader where it's  
been cut after I shoot the roll, so there's no doubt. It's something  
I learned from the Voigtlander Prominent, which folds the tip enough  
when one loads it.
When the B&W piles up for a run through the Diafine, I can tell which  
came from which camera by looking at where the fold in the leader is.
