Smith & Wesson Model 53, .22 Magnum/.22 Jet cal. revolver. Serial # K442003, mfg. 1961.  Excellent condition.  Very nice Jet! These are becoming harder and harder to find and this one is a dandy with all the goodies! Yee haw! Blue finish is 97% with some wear on the back strap and a cylinder ring. Adjustable target sights. Wide target hammer and trigger with shoe.  6” barrel has an excellent shiny bore.  Smith and Wesson monogrammed checkered grips are excellent. Includes a .22 Magnum cylinder and the .22 Jet  cylinder with six chamber inserts.  Factory box is not labeled and is in excellent condition. Manual and paperwork. Doomed to fail from the get-go, this made the Jet an instant collector's item! C&R OK.
