I bought a well worn Confederate longarm from a reputable dealer many years ago. It had a somewhat common name carved in the stock. The dealer I bought it from priced it for its extrinsic value alone because he explained there was no way to link the gun or military service to the carved. I subsequently traded the gun and several weeks later it turned up on another dealer's table at a show being sold at 3X what I paid as an identified firearm, complete with a stack of records showing the war record of a soldier who had the same name. When I played dumb and asked about the provenance -- repeatedly -- he finally said it was the only person with that name who served in the CSA and from the state where the gun was manufactured. It was an invaluable lesson that for once did not cost me anything.
