My step-dad was given an old Smith and Wesson revolver today by one of his patients. I was wondering if I could get some information on it? The markings on it consist of +Smith & Wesson Springfield Mass U.S.A.+ on the top of the barrel 38. S.&W. CTG on the left side of the barrel The serial Number is on the base of the grip, it is 2276XX the revolver is a nickel plated top break. This pistol was coincidentally owned by an ancestor of my stepfather which is why it was given to him. Any information that the members of this board could provide would be appreciated.
