Serial # NSN Complete throughout. Possibly American made. Unmarked. Features a 42-1/2" barrel, smooth bore, .75 caliber, and an iron barrel with a top-mounted bayonet lug. American walnut full stock of typical provincial "Brown Bess" inspired design, with a pronounced comb and simple molding around the lock and sideplate. Rare recycled English pattern 1742 lock with traces of its markings and original components: the frizzen spring may be an American working life replacement? American sheet brass hardware. Three barrel-form ramrod pipes, a simple finial trigger guard, a French-style "S" shape sideplate, a pin-fastened nose cap and the screw-fastened buttplate. The furniture with a dark untouched age patina, some light verdigris and patches of darkness. In overall very good untouched original flintlock condition. The barrel with chocolate brown surfaces and moderate scattered pitting. The lock with matching patina and in non-fuctioning order, as the hammer has slipped off the tumbler. Untouched hardware with matching smooth, mustard-toned surfaces. The stocks with scattered handling marks, some minor abrasions, chips, expected signs of use, and 65%+ finish. In original flintlock configuration with a fine touch-hole. Retains what is possibly the original wooden ramrod with iron jag. Overall length 57-1/2". a very nice example of an American made Revolutionary War "COS" musket.
