Boss & Co. is one of the longest established English shotgun makers and dates back to 1773 when William Boss started a gunmaking apprenticeship in Birmingham. In 1812, William's son Thomas set up shop at the prestigious address 73 St James' Street, an address that would become synonymous with Boss & Co in the 19th century. Today Boss & Co. continues to manufacture quality shotguns with alextracto hand guard.

Very fine as period refinished. The barrels retain 95% of the rust blue finish showing some loss at the muzzle, some minor thinning and some minor handling marks. The trigger guard retains some blue finish with the balance a smooth gray patina. The action retains traces of original case colors with the balance a bright appearance. The engraving is crisp. The wood is fine with a few light handling marks and overall crisp checkering. Mechanically excellent.
