Let's say an original .45-not A1, just 1911 that was brought home by somone after the war and the numbers were removed? (Not related to my other post) Isn't there some kind of acid that could be dripped on the number to bring it back out so it could be re-stamped? Is there anyone out there in the gun world that could do anything with this other than go to jail for owning it? I understand back after WWII, some GI's were told they could keep their guns, but they had to remove all military markings, thus in the modern times, you now have an illegal gun.
