1931 G.A. Krauss Peggy I is the first of the Peggy series which began with the viewfinder only Peggy I and the rangefinder version, Peggy II. In 1933, the Peggy Norm was introduced which was similar to the Peggy I but had all the updates of the Peggy II, minus the rangefinder.  A rangefinder could be retrofitted by Krauss for an additional fee. This camera was available in either black with nickel fittings or in chrome. The Peggy I is a very well made camera of about the same quality as the Leica I(A) of the time and predates the Contax by one year. Notice that focus is achieved by moving the (operator's) right knob on the top plate. As the knob is turned the lens board moves in or out as the case may be. The small knob resets the film counter and the large left knob both advances the film and cocks the shutter. The lens is a Carl Zeiss Jena Tessar f3.5 / 50mm in a Compur shutter. The large knurled ring around the lens can be turned to set the shutter speeds and the f stops are changed by moving the pointer in the curved slot inside the knurled ring.
