Below: Camera as it arrived with incorrect chrome speed dial.
This camera also has the rear plug as well as the pressure plate access port which was only used in combination with the early standardized Elmar lenses where the true focal length varied a few mm's. The 5cm Elmar here is a standardized lens but also has the Leitz code engraved on the rear of the focusing lever. This code identified the true focal length of the lens and permitted final adjustment of infinity focus.Both the engraved true focal length code on the lens and the pressure plate access port appeared for only a brief period and are not commonly found on the IID and Elmar lenses.
In the earliest examples of the Leica II(D) as shown here, there was a plug in the back of the camera body (see above) which had been used on non-standardized Leica models A, B and C for final lens adjustments. This was accessed through the film pressure plate by means of an access port as seen here. The presence of the access port indicates that the pressure plate had actually been produced for the earlier Leica model.
The nickel 5cm f/3.5 Elmar (130,736) is among the earliest produced for the coupled rangefinder. These are marked by the 11 o'clock infinity lock and the bell-push release button.
