[Leica] M3 purchase

[jbcollier at shaw.ca (John Collier)]

All the M4-2 and up cameras have steel winding gears. Brass doesn't 
hold up when a motor/winder is attached. I think the motorized M4s and 
M2s had steel gears as well. I even think, but am too lazy to look it 
up, that the original MPs did too.

Someone blast me if I am mistook.

Steel gears take longer to wear in. My TTLs are quite smooth now that 
hundreds of rolls have run through them.
