I'm not Geo, but what he's telling you is that the weapon was proofed (test fired and stamped with a "proof" mark – usually but not always coinciding with the year of manufacture) sometime in the mid 1960s. It was "surplussed" (meaning replaced by another weapon and subsequently stricken from the police inventory; over here our federal government refers to this as being "excessed") probably in the late 1970s to early 1980s. After it was surplussed it was refurbished, exported, and sold on the civilian market.Geo, what's that mean? Thanks
It's probably better to say that these date codes are stamped on the frame of the gun. The barrels themselves show the nitro proof mark only....the German government proof is the date that you see on the gun and/or barrel, which is usually the same year as the gun was built.
