Smith & Wesson Model 48-4 "K-22 Masterpiece", .22 magnum cal. double action revolver. Serial #78K1679, mfg. 1980.   Like new condition.  8 3/8" barrel has excellent bore, ramp front sight and micro-adjustable rear.  Barrel and frame have near 100% blue finish with crisp markings.  Case colored trigger and hammer are 100%.  Gold S&W monogrammed checkered target grips are excellent! Gun appears unfired.  Unusual barrel length for the .22 magnum – nice collector piece!
