"I, too, suspect that Erwitt's Leica has been customized. Brassing should only occur where the camera comes in contact with another object, i.e. skin or strap. Notice where it is brassed on the front and top. It is in areas normally not handled."
Agreed. Never noticed that before, good observation. Also that, on the top, all the text is still unbrassed, while all around it is totally brassed.
Still lovely but faked.
