I’m trying to identify the model of a camera Leica, but I’m not being very much successful.
This is an early model, all black, with Leitz Elmar f: 3,5/50mm lens, but unfortunately I can’t find any serial number on it. I’ve already opened it (the bottom), since I’ve read that the serial number could be inscribed in the interior, but I didn’t see anything.
It has no inscriptions.
How can I identify this model?
