When I was much younger two things would improve the used gun values. If it were a Browning Super and the tag came along with the gun and it had not been filled in it would bring a bit more money. The second thing was any pistol which pre-dated 1968 fire arm act and had never been registered. Long guns were not as valued but unregistered pistols certainly were. In fact I doubt nay of my fathers hand guns or long guns had been registered when bought because there were no registrations back then. As to the Browning the friends who shot them a lot had very, very few problems with them that ever required repairs. The odd firing pin might need to be replaced but they all were before the salt wood problems.
