Originally built as a 20 gauge gun, this gun has had a set of 28 gauge barrels added and upgraded to the configuration. The gun has Winchester Proof Steel barrels with dual bead sights on the matted concave solid rib which is marked "CUSTOM BUILT BY WINCHESTER", 3 inch wedges of floral scroll engraving at either breech, chokes marked "WS-1"/"WS-2", and 2 3/4 inch chambers with automatic ejectors. The barrels are fitted to a blued boxlock action which displays beautiful Winchester 21-6 pattern engraving consisting of near full coverage floral scrollwork surrounding attractive game scenes. The left side shows a setter in a field scene, the right has a pointer in a field scene, the underside shows a pair of pheasants in a field scene, and a bust of a dog on the triggerguard all rendered in fine detail. The gun features a gold plated single selective trigger and tang mounted automatic safety with gold inlaid "SAFE" indicator. The gun is mounted with a beautifully figured and multi-point checkered beavertail forend with engraved fittings and ebony tip inlay as well as a pistol grip stock with matching checkering, factory hard rubber grip cap, "H.Y." in the inscription oval, and a leather covered rubber recoil pad. Included is an added set of 28 inch 28 gauge barrels with matching engraving and featuring 2 3/4 inch chambers and chokes marked "MOD"/"FULL". Also included is a wood and leather takedown case, with silver plaque inscribed "G. F. Tyson", that houses the entire set and a Cody Museum order sheet which confirms the two barrels (though both are listed as 20 gauge), engraving, chokes, barrel lengths, sights, and stock when it was completed on January 4, 1938. Barrel measurements for the extra barrel set (R/L): bore diameter nine inches from the breech .548/.548 inches; choke constriction .013/.025 inches. Barrel and stock measurements (R/L): bore diameter nine inches from the breech .621/.618 inches; choke constriction .004(jug)/.011 inches; minimum wall thickness .026/.026 inches; 1 1/2 inch drop at comb; 2 1/4 inch drop at heel; 14 1/4 inch length of pull; weight 7 lbs. 3 oz.

Very fine as professionally upgraded to current configuration retaining 95% of the refinished blue finish with minor handling evidence, browning around the rib marking, a few dings and scratches on the wood, compressed recoil pad, and sharp checkering on the otherwise fine wood. Mechanically excellent. The case is fine. The extra barrel set is very fine.
