John Hall's London shop was active from the early 18th century until around 1770, even though he died in 1740, and is known to have manufactured brass barreled blunderbusses. The flared muzzles made reloading much easier on horseback or on the rolling seas, and the primarily brass fittings were more resistant of salt water corrosion. The barrels have 1.1 inch inside diameters at the muzzles and approximately 16 gauge (.65 caliber) bores. The tops are inscribed "London," and the left sides at the breech have London Gunmakers' Co. private proof and view marks flaking a gunmaker's hallmark that consists of a crown over an illegible letter (likely "crown/H" for Hall). The locks are inscribed "Hall" ahead of the cocks. There are some engraved floral accents throughout, and the trigger guard has an acorn finial. The stocks have shell carving at the barrel tangs and ornate thumb plates.

Fine with attractive aged patina on the brass, gray and brown patina on the iron, some light oxidation, and scattered marks and scratches. The re-oiled stock has cracks to the left of the trigger guard up to the side plate and at the screws, a repair at the butt, minor chipping around the lock inlet, and several small dents and scratches. The carving and markings are crisp. Mechanically fine.
