A late war SV Victory. Without a factory letter, pinning down a shipment date on an SV is difficult, but this SN is likely to be from early 1945. SVs started at the beginning of 1945, allegedly at SV 769001 or thereabouts. Many left-over SV-prefix frames were finished in civilian form by S&W and sold on the open market in early 1946. Yours is apparently in military style, but you did not mention if it has the U.S. Property stamp on the top strap. I think that one would be an ideal candidate for a do-it-yourself Parkerizing job and refinish/replace the service grips. At least that's what I wold do with it - Bead blast and Parkerize.
