The serial number dates to 1916 and subsequently extensively upgraded to its current "F Grade" configuration with blued barrels featuring dual white bead sights on the matted concave solid rib which shows a gold inlaid bar at the base along with a flourish of scroll engraving, "KRUPP FLUID STEEL MADE BY" and A. H. FOX GUN Co. PHILA PA." marked on the right and left tubes respectively, and 2 3/4 inch chambers with automatic ejectors. The barrels both show a single band of engraving at the muzzle and a 2 1/2 inch wedge of floral scroll engraving inset with a beautifully executed gold inlaid lightning bolt. The barrels are mated to a casehardened boxlock action which displays highly attractive floral scroll engraving incorporating a gold inlaid setter on point on the left along with a flower, a gold pair of quail in flight on the underside, and a gold inlaid retriever on the right as well as a second flower. The triggerguard is inlaid with a gold inlaid set of initials "DFD" and the serial number is in gold on the lower tang. The gun features a single selective trigger and a tang mounted manual safety with a gold inlaid "SAFE" indicator. The gun is mounted with a beautiful highly figured and fancy fleur-de-lis checkered splinter forend with engraved fittings and an ebony tip inlay and a round knob pistol grip stock with checkered flats and a serrated hard rubber buttplate. Included is a second set of 26 inch 12 gauge barrels numbered to match and with matching engraving and inlays. Barrel measurements for the extra set (R/L): bore diameter nine inches from the breech .731/.730 inches; choke constriction .004/.007 inches; minimum wall thickness .029/.026 inches. Barrel and stock measurements (R/L): bore diameter nine inches from the breech .733/.731 inches; choke constriction .008/.012 inches; minimum wall thickness .024/.027 inches; 1 9/16 inch drop at comb; 2 1/2 inch drop at heel; 14 7/16 inch length of pull; weight 7 lbs. 7 oz.

Very fine as professionally upgraded to its current configuration, retaining 99% blue and gold finishes, flashes of case colors on the action, minor handling evidence, and sharp checkering on the stock and forend. Mechanically excellent. The extra barrel set is also very fine.
