1913 DWM

Murry, You don't mention if the serial numbers of your luger match, but if so it sounds like an unaltered one. So, I'd bet that it came back after WW1 rather than WW2. It would certainly give the pistol more flare, if you could trace it back to the Anzac who might have brought it back from Galipoli. If your registration laws go back that far, it might be worth checking with the "Gov".
