Here's another printable Leica brochure from my wee collection. This one features the M4-P that was reputedly a cheaper-made version of the original M4, which probably means it's only twice as well made as contemporary cameras.
Not sure about the winder, though. Maybe if it was only half as tall it wouldn't be so bad but it does make a big difference to the size of the camera, doesn't it? Anyway, if you're a Leica fan then enjoy.
