Blued Winchester Proof Steel barrels with single red bead sights on the matted vent rib which is marked "CUSTOM BUILT BY WINCHESTER", "1" marked on the forend lug, 3 1/2 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 blued boxlock action displays gorgeous Grand American pattern engraving consisting of near full coverage floral scroll engraving surrounding four gold inlaid game scenes. The left shows a setter in a field scene, the right has a pointer in a field scene, and the underside shows a pair of pheasant in an upland scene, and a bust of a pointer on the triggerguard all rendered in highly detailed gold inlays. The gun features a gold plated single selective trigger and tang mounted automatic safety switch with gold inlaid "SAFE". Beautiful, highly figured, 21-B pattern fancy fleur-de-lis checkered beavertail forend with engraved fittings, rotary latch release, and ebony tip inlay. The pistol grip stock is of the same exceptional quality with matching fleur-de-lis checkering and engraved and gold inlaid "GRAND/AMERICAN" grip cap, blank gold inscription oval, and checkered bare butt. Included is a second 26 inch barrel set in 28 gauge with matching serial number and engraving ("2" on the forend lug), 2 3/4 inch chambers with ejectors, chokes marked "WS-1"/"WS-2", and matching beavertail forend. This is a rare example of a lightweight 28 gauge Model 21 as most of the 28 gauge 21s were built using 20 gauge barrel blanks bored to 28, making them heavy and unwieldy. It is estimated that 7-10 guns were built with these lighter tapered barrels per an included copy of a document from late Winchester employee and Model 21 expert Edward E. Ulrich. Included is a Winchester leather bound takedown case with canvas cover, four snap caps (two 28 gauge, two 20 gauge), cleaning tools, and an excerpt from an autobiographical article in the Autumn 1999 issue of "Double Gun Journal". Barrel measurements for the 20 gauge set (R/L): bore diameter nine inches from the breech .551/.551 inches; choke constriction .006/.011 inches. Barrel and stock measurements for the 28 gauge set (R/L): bore diameter nine inches from the breech .623/.624 inches; choke constriction .007/.015 inches; minimum wall thickness .029/.032 inches; 1 7/16 inch drop at comb; 2 1/4 inch drop at heel; 14 1/2 inch length of pull; weight 7 lbs. 2 oz.

Very fine overall as custom embellished to current configuration, retaining 99% blue finish with some minor areas of gold loss on the underside of the action, plum hue to the action and grip cap, minor handling evidence, and sharp checkering on the stock and forend. The extra barrel set, case, and accessories are also all excellent. Mechanically excellent.
