The classic Leica M3 is Leica's first M-mount camera, and it's still one of the most usable "classic" cameras out there. This is a 1955 model by serial number, but it's been modified at some point in its history with M4 components, including a single-stroke winder (with an M4 lever) and new self timer and frameline preview levers. Purists may complain, but it's no great crime to add a more comfortable winder to an M3. In any event, shutter speeds are accurate, the rangefinder is clear, and cosmetic condition is excellent, with only light finish wear and a tiny ding on the top plate.
