Score: S&W US Model of 1917 .45 ACP Revolver,

[Salt Flat]

Sweet, I bought a Smith & Wesson Victory model in the 70,s. It had "Civil Defense" crudely inscribed on the left side, done with a vibrating engraver. Yours looks much nicer. They had a whole display case full of them. 35 bucks each at Warshal's Sporting Goods in Seattle. Shot the heck out of it.
