Boss & Co. are among the finest builder of fine arms in the world, and have been since the company was established by Thomas Boss in 1812. This gun was built between 1921 and 1925 per the information given on page 238 of Donald Dallas' "Boss & Co.: Makers of Best Guns Only", right in the heart of the golden age of English gunmaking. This gun is a prime example of the level of quality produced by Boss & Co. and would be a great addition to any collection of fine sporting arms. Built with blued steel barrels featuring a dual bead sights on the matted flat solid rib, "BOSS & Co." and "13, DOVER STREET , PICCADILLY, LONDON. ENGLAND" marked on the right and left of the upper tube receptively, scroll engraving around the breech, London proofs on the flats and right of upper barrel, and 2 1/2 inch chambers with automatic ejectors. The barrels are fitted to an attractive casehardened sidelock action which displays extensive bouquet and scroll engraving surrounding bright and nitre blue action pins, "BOSS & Co." signatures in banners on either lockplate, and patent marking on either side of the receiver before spilling onto the triggerguard, both tangs, and the toplever. The gun features gold centerline cocking indicators, double triggers, a right hand rolled triggerguard, and an automatic tang mounted safety with gold inlaid "SAFE" indicator. The gun is mounted with a beautiful highly figured and multi-point checkered forend with engraved fitting, elongated shoe, and an Anson button release as well as a round knob pistol grip stock with teardrop carved drop points, gold inscription oval marked "S.M.B.", and a checkered bare butt.
