Nominally .50 caliber, .85 at muzzle. 6" octagon to round wedge retained barrels with baluster turned transitions. NSN. Brass barrels, steel lock, brass furniture, hardwood stock. Single shot flintlock smooth bore cannon muzzle pistols with spring deployed bayonet. 3.85" flat, stepped and bolted flint locks lightly engraved and somewhat crudely marked H COOK. Locks remains in original flint with flat bottom and fenced iron pans with roller frizzens. Plain swan neck cocks. The interiors of the locks and tops of the bayonet locking lugs show the matching assembly numbers 19 on one gun and 27 on the other. Barrels with no visible proofs and showing depressed maker's marks of a {Crown} and a {Fleur-de-Lis}. Breeches with what appear to be Irish Registration numbers, DC-168 and DC-171, indicating registration in Dublin City during the 1843 Registration Act. Pistols are equipped with a 5" snap bayonets with a 3.75" triangular blades, with the releases mounted on the breech plug tangs. Pistols include brass tipped wood ramrods. In the absence of English proof marks and considering the somewhat crude construction when compared to similar guns from Birmingham or London, it seems likely these are of Irish origin, or possibly French due to the barrel markings, but the Cook name seems unlikely in that case. A neat pair of Irish registered snap bayonet flint pistols that display nicely.
