These guns were never Military issue, however they were used by the R.F.V., Reichsfinanzverwaltung , ( the Federal Finance Administration ). If there are R.F.V. markings , perhaps it was taken from a captured finance clerk. More likely it is a civilian purchase that may have been carried as a personal firearm by a German soldier or perhaps one that was confiscated from a private residence. But who knows, it may have been taken from a raving insane SS Colonel in hand to hand combat.
