This is a genuine US 1917 with a lower s/n - 21,xxx. Likely a 1917 production. Numbers match on the frame/barrel/cylinder/ejector. Grips are genuine Smith and Wesson for the gun but number to a higher s/n, though they fit nicely. $600 ftf eastside of Seattle in WA or $25 shipping to an FFL outside WA. Mechanics: The gun is in very good to excellent mechanical condition. B/c gap is .004/.005" with about .002" of endshake. Headspace is excellent. Bore is a little dark but would clean nicely and has good lands and grooves, muzzle is nicely shaped without damage. Trigger is smooth and consistent - gun still has original military mainspring and thus a slightly heavier trigger pull like the original design. A modern commercial mainspring could be installed to make a lighter trigger action. Cosmetics: Gun has 75% or more of an older, very professional re-blue on it. Hard to notice at first it is a re-blue until close examination shows lightened marks of the "S&W D.A. 45" on the barrel, and one side of the barrel pin flattened (right side). Gun has some mild pitting on sides of barrel, blue is worn on grip straps front and rear, top strap, and sides of barrel. Trigger/hammer still have faded but present case hardening intact. Patent dates on top of barrel and "U.S. Property" marks on underside are crisp and sharp (will try to get a good photo of them later). Grips' condition matches gun and fit nicely, though numbered to later gun. Unfortunately, the butt swivel was removed, a plug brazed in, and the grip end ground smooth. The s/n on the grip is thus very faint and the "US ARMY" mark mostly gone, but traces visible. The "GHS" inspector's stamp is on the top left of the frame, and there is a perfectly stamped "2" on the lower right corner of the frame. No other martial marks. Price: I see excellent original ones $1500 to $2000, and beater ones needing much work at about $500. Ones in similar condition with original finish at about $900 to $1100. I'm thinking $675 for a genuine US military model in this condition, and not a later civilian or Brazilian model, is fair. Will try to add more detailed close-up photos of bore, ejector, marks, etc. if I can pull them off.
