I had an 1892 Winchester in .38WCF, and a fellow I sort of knew came over. He eyed the firearm, not saying much -- but returned two days later with friends (cousins) who collect these. I was asked NOT if I wished to sell or trade it, but more "what will you accept in trade." Giving but a few moments of (probably the best choice to be made) thought, I asked for a ,45 revolver. An hour or two later they came back and presented me with a fair-condition revolver, and sped off with the .38-40. A bit nervous with an unregistered revolver, I did in fact register it -- to be visited by police a few weeks or so later, where I was given the choice of giving up the revolver or, being in possession of stolen property. I chose the former. This was in 1970 -- it still bothers me.... and, I still miss that Winnie...
