Bob & jsmith, I'll check with the collector and see what background is known about the gun #0172. He said he bought it from a another collector ( not a S&W collector) who didn't know what much about it and thought it was a new Model #3 in 38-44 cal. He bought it for peanuts in relation to what it is worth, if it's really a club gun shipped to D.B.Wesson. As we know, Club guns, or "0" guns were usualy presented to some shooters event or Club for shooting prizes, and an entry of "D.B.Wesson" as recipient ,often just meant that DB presented the gun to the Club.
