The frame was manufactured in 1898 per information listed on page 236 of Donald Dallas' "Boss & Co.: Builders of Best Guns Only" with a set of replacement tubes with London nitro proofs built in the 1960s numbered both "9485" as well as to the frame "4600". The gun has blued steel barrels with a single bead sight on the smooth concave solid rib which is marked "BOSS & CO. 13/14 CORK STREET. LONDON. W.1." along with a gold "2" at the base, 2 3/4 inch chambers with automatic ejectors, and light engraving at the breeches. The coin grey finished sidelock action displays classic bouquet & scroll engraving with "BOSS & Co." banners on either lockplate and "BOSS'S PATENT" marked on either side. The scroll extends to the trigger guard, both tangs, and the toplever which has a gold "2". The gun features a single trigger, lockplate mounted selector, gold centered cocking indicators, and a tang mounted manual safety with gold "SAFE" marking. Beautifully figured, multi-point checkered splinter forend with engraved fittings, including the Anson button release which is also marked with a gold "2". The straight grip stock is of the same quality with teardrop carved drop points and a checkered bare butt. Barrel and stock measurements (R/L): bore diameter nine inches from the breech both proved at .662 inches and both measured at .664 inches; choke constriction .006/.017 inches; minimum wall thickness .024/.023 inches; 1 1/2 inch drop at comb; 2 1/8 inch drop at heel; 14 1/16 inch length of pull; weight 5 lbs. 11 oz.

Very fine as refurbished, retaining 90% plus blue finish on the barrels, distinct areas of dark blacked and fading plum finish on the trigger guard, smooth coin grey color on the action and sideplates, some thinning on the left barrel, and overall light handling evidence. The wood is also very fine with a few small dings and scratches and sharp checkering on the stock and forend. Mechanically excellent.
