I have in my collection a somewhat unusual Mauser M-1914 in 7.65mm. (Serial # 123520 ) It has C/U & WW1 era Imperial military proofs. What's unusual is that it's unnumbered barrel is E/N proofed, and has the late style, rounded "half moon" type front sight blade. ( As opposed to the earlier style, ramp front sight.) The wear on the bbl matches the weapon's overall condition perfectly, and in no way appears to a recent replacement. Other than the above noted proofs, it exhibits no additional police or military markings. The pistol was purchased directly from a veteran's widow, who knew only that "he took it home from France after WW2". Could this Mauser have been a WW1 Officer's personal sidearm, that was returned to Mauser for a barrel replacement sometime after April 1940 ? Any comments will be deeply appreciated. THANKS.
