Manufactured circa 1966 as part of an unknown (likely limited) quantity manufactured for the second contract to the Sultanate of Muscat and Oman, with the actual number of delivered pistols unknown at this time. Features fixed serrated blade front and adjustable tangent rear sights (graduated from 50 to 500), extended magazine, shoulder stock slotted frame with left side lanyard loop, matching serial numbers on the sight side of the barrel, slide, and frame, along with "crossed swords/Jambiya" seal of the Sultanate of Oman on the right side of the slide. Includes an oiled walnut board shoulder stock with unnumbered iron and attached leather flap holster, and extra magazine, along with photocopy of the BATFE C&R exception list for the NFA verifying that the shoulder-stocked Muscat & Oman High Power pistols as acceptable without a tax stamp.

Excellent, retaining 98% original blue finish with minor oxidation on the slide and frame, some minor thinning around the shoulder stock slot, and otherwise limited handling evidence. The grips are also excellent with well defined checkering. Mechanically excellent. The board stock's iron will not fit in the pistol's connection slot, otherwise it and the holster are excellent.
