Hi Robert,
The RC Proof indicates a review ( Arsenal Rework ) by the Revision Commission. You sholud find this small proof elsewhere on your pistol ( right receiver, front of trigger guard...). As for the GERMANY stamp, I have seen it mostly on commercial models ( like a 1920 ) but not on a military piece...I'd be curious to see it. Can you post some PICS?? It would help on the ID...
