High Standard Sentinel Mk IV in .22 WMR. Overall this gun is in low good condition. Mechanically it functions as it should. The bore is bright and mirrorlike with strong lands and grooves. The revolver retains about 80% of its original blued finish. There is substantial wear on the wood grips, particularly on the right side. The revolver features a two inch barrel, a nine round cylinder, and a DA/SA trigger. This would make a suitable carry revolver.
