Manufactured around 1770-1800 with "London" on the right side of the action along with some light engraving, "Blair" and light engraving on the left side of the action behind the pan lever, a single cock and frizzen, sliding safety catch, single trigger, and a walnut grip. The breech at the top has a pair of "2s" and the bottom has "3s" and a cross scepter proofmark.

Fair. The metal has pitting, oxidation, and a dark patina overall. The markings and engraving patterns are mostly crisp. The grip is fine and has several scrapes and dings. Mechanically fine.
