This c. early 1800s British blunderbuss is signed "Thomas" on the lock and has Ordnance private proofs on top of the barrel at the breech. Various makers made/sold blunderbusses of this pattern based on others with various markings. The muzzle flares to approximately 1 3/8 inches at the muzzle, and the barrel has a sprung bayonet mounted underneath that is secured via a catch in the forend cap and released using the trigger ahead of the trigger guard bow. The barrel also has a left side mounted ramrod and some light engraved borders. The lock has a stepped tail, light engraving, sliding safety catch, a semi-rainproof pan, frizzen roller, and frizzen spring with light hump for the roller. The brass furniture has some light engraving. The stock has a finely checkered wrist with incised molding.

Fine with attractive aged patina on the brass barrel and furniture, dark brown patina on the lock, lighter patina on the barrel tang and bayonet, some patches of mild pitting, and mild overall wear. The stock is good and has crisp checkering with some minor spots of wear, minor flakes at the edges, repaired cracks at the wedge, and general scratches and dings. Mechanically fine.
