High Standard Sentinel MK II, .357 magnum cal. double action revolver.  Serial #H31203.  Fair condition.  4” barrel has well-worn bore, fixed sights.  Barrel and frame have 40% blue with numerous hits and dings.  Cylinder is 30% with index marks and lots of corrosion.  Smooth contoured walnut grips have good finish with a crack on left side.  Double action works fine.  Still a good shooter.
