An S&W .45 ACP Moonclip revolver I briefly inspected over the weekend. Family legend claims it served in WWI. Note the notches on the handle(!?)
It is double action and stamped with some notation on the barrel “Smith & Wesson 1950 Barrel”. (Not the exact phrase)
So I throw the question out to the blogosphere: is this revolver as old as claimed? Is there a definitive test for age?
