The Leica M3

The Leica M3 camera was introduced in 1954,
The first production model being number 700 000, last number 1 158 995 when general production ceased in 1966.
The Leica M3 was the first production model using a bayonet type lens mount, a 30° turn locking the lens in position.

Viewfinder / range finder system sharing a common eyepiece with bright line frames for 50,90 and135mm focal lengths, each with automatic parallax adjustment.
A rapid wind lever which with two short strokes wound on the film and tensioned the shutter.
On changing the film the counter reset automatically to -2 and the camera back  was hinged to provide access for film loading.
Flash synchronization  is automatic, separate contacts for expendable and electronics flash units The shutter speeds from B to 1/1000 of  a second are incorporated in a single dial.
There were some variations during the production run and I would like to illustrate them in the same time as the 35mm focal lengths and coupled Leicameter.
