Robert: You are probably right. I have the gun in front of me at the moment. It is marked: "A B T SOMMERDA" on the left barrel & "RHEINMETALL" on the left & "EHRHARDT LAUF" on both. The barrel flats have a number of markings such as: "3 TONS, NP, 729, 12" & various proof marks. The SN is 41506 with only 506 on the fore arm iron. Above the tang safety is the word: "Sicher". The gun has automatic ejectors & Greener cross-bolt. Any info that you might have would be appreciated. Same to you Jagermeister,
Best Regards, George L
