Leica IIIb with Leica Mooly motor

Description
The Leica model IIIb introduced an eyepiece diopter adjustment lever under the rewind knob. With this lever it was possible to adjust the sharpness of the viewfinder image to a person’s eyesight. However, the most important feature of this Leica is the attached Leica motor (code name MOOLY).
The Mooly clockwork motor mechanism on this early production model from 1938 is capable of driving an attached Leica camera at two frames per second for up to twelve frames. The earliest motors up to serial no. 400 had two speed motors for one or two frames per second. But by serial no. 634, the button on the front of the motor had been disabled and only two frames per second was available. The button was removed on later production motors.
