Ohh my, I just saw this, sorry..............Hmmmm this camera is a STRANGE BIRD!
First of all it's a REPLACEMENT top plate camera (postwar "stepper" factory redone) from a damaged or perhaps a real HEER camera?, note the Nr. before the serial number, this is a 100% giveaway that the camera has been repaired/has a replaced top from the factory.
Normal Leicas have no. before the serial number, also look at the strange gap between the 3 numbers, odd.
The numbers fall into the right era for Heer engraving, this was more than likely a Army camera that was de-militarized by the factory.
I DON'T buy the paint though as original factory though, it is thin and also the factory never used chrome screws to finish painted cameras.........and the case I think has been *newly stamped* Heer
I think that this camera was originally a Grey Heer camera (extremely rare) which was sent back to the factory ca, 1951/52 to be redone in chrome with a replacenment top and bottom plate and somewhere along the way the camera was painted Black by someone.
It was a odd camera (catch 22) and it made a little more $$$$ than I think it's worth, but if the lens turns out to be a real Heer it's worth MORE than the camera is!
