Last spring I bought a chrome Lufttwaffen Eigentum IIIC that had been defaced. Only the "m" at the end of the "Lufttwaffen Eigentum" inscription remained readable. The FL number is still on the top plate.
I contacted Jim Lager and he confirmed that my camera was delivered to Berlin in December, 1940.
The camera was a bit of a mess - missing Vulcanite, gooey red curtains, and a lens mount flange that was rotated 90 degrees from where it should be! I suspect that someone had tried to repair the camera, gave up, and put the lens flange back in a hurry.
I sent the camera to DAG, who replaced the curtains with "like new" used red curtains, recovered the camera with material that is remarkably like the original Vulcanite, and did a CLA. The camera had already been worked on so I didn't feel bad about trying to restore it to a useful life.
The camera came with a 1939 Elmar. I haven't determined if that lens was original. I also received a grey case with a cut slice on top where the "Luftwaffen Eigentum" inscription would have been. It's a bit of a mystery to me why the case has the standard nose (vs. the flat nose) while the lens is an Elmar. Perhaps the case, lens, and body weren't originally together?
Anyway, that's my story about this camera.
