The Leica M4 is a classic 35mm rangefinder camera, as you may already know. This one is in excellent cosmetic condition, with only minor wear on the top panel, slightly more wear on the base- but no dents or dings, just rub marks from normal use. This M4 is an original German-production camera, and it's just back from a full professional CLA. It's a heck of a camera, ready to shoot, with accurate speeds and a calibrated rangefinder. If you were going to ask, the answer is 1968.
