About six years ago a hock shop had a Colt 1917 hanging on the wall. The outside looked fine but it had a modified Pachmayr grip for a Ruger Red Hawk on it. The price was $599. I looked down the bore and couldn't see any rifling. It looked like heavy lead build up. I passed on it. A few months later it was priced at $499. A couple of months later it was at $399. I knew a gunsmith that had a Colt New Service barrel for a 45 Colt that he would let me have for $75. I talked to the pawn broker and got it for $400 out the door. Went home and ran a bore snake down the barrel and out came a wad of oily fuzz bunnies. The bore looked like it did in 1918. Someone had oiled the bore and put it up for years and it had accumulated a lot of dust and fuzz.
