The early Mauser rework would explain the C/c/U, right? But as I stated it's a 7.65, so that makes it a civilian, right? But why would it's parts be serial numbered like a military pistol and why would it have what are seemingly military proofs?
I'm hesitant to speculate given that I'm such a rookie when it comes to these pistols, but could it be that at some point it was a 9mm and in some military arsenal, but then re-barrel by Mauser to 7.65 for civilian sale?
But if it was built as a military weapon wouldn't it have the date stamp on the barrel crown? Or could it have been built as a civilian pistol, been drafted into service and changed to 9mm and at that point had the parts numbered and the proofs added, then re-worked back to it's original civilian caliber?
