I just bought this a few days ago. The serial # is 105xxx, which dates it to 1916. The bore is as nice looking as the rest of it. It was originally .455 Eley, but was re-chambered to .45 Colt. The grips are real stag, and are marked, "Harrelson,R.L., USN" on the inside of each panel. I believe I stole it at $450!
