No, not rare at all. The Crown/U is found fairly commonly on EG Lugers. Usually on the left receiver near the serial number or below the serial number on the rail.

The Crown / N on the barrel is common also, indicating an EG replaced barrel. The EG C/N is of a slightly different style than the commercial DWM C/N, but similar.

One interesting thing about VoPos is that very rarely will two Lugers have the same East German markings in the same place, or even bare similar markings. It's as if they just stamped them haphazardly , if they stamped them at all.

The one outstanding feature on yours, is the unaltered/ uncancelled Police "Sun Burst" property mark on the frame. It probably went unnoticed due to it being behind the TD lever.

This in addition to the uncancelled Reichswehr unit mark on the grip strap make it unusual.

Back to the WWII Waffenamt on the grip. It's not likely that those grips were on it when in Russia or EG. The Russians hated the Nazis, and would go to great lengths to obliterate any Nazi markings on captured weapons.

I just noticed the Russian / Bulgarian? extractor in your photos. Another plus.
