I came across a gentleman selling his late mother's camera on Craigslist just now. He isn't sure what he is selling, but it seems to be a military Leica with the ball bearing upgrade. I think this is a real deal so I told him I would help him verify the authenticity... because if it's real, I think this worths way more than what I can offer to him!
Mechanically the camera definitely needs some CLA, VF looks a bit unclear, and the lens (an Elmar that also bear the marking of Luftwaffe-eigentum) have a bit of dust and maybe some haze too. But cosmetically this camera seems to be in really good shape. It even comes with a Luftwaffen-eigentum leather case, plus a Gossen light meter, and even the box. The camera could even come from someone in his family who served in the air force around WW2 time. All these tell me it's a real thing. What do you think this worth?
