.49 caliber. 42.325" three-stage pinned octagon to round barrel. SN: NSN. Bright finish, brass furniture, smooth faux striped hardwood stock. Unmarked commercial single screw, single trigger percussion lock, barrel marked "H GIBBS" on top flat. Brass furniture includes a spurred triggerguard, buttplate, toe plate, a ramrod thimble and an entry pipe. A sheet brass saddle plate has been added to the belly of the stock, forward of the triggerguard. Forend shortened between 5" and 6" with pin lug removed from barrel. Henry Gibbs (1824-1880) worked as a gunmaker in Lancaster, PA from the 1850s-1880s. The form of the gun is that of a later pattern, inexpensive trade gun rather than one for general commercial sale, with the multi-stage barrel being completely out of date for an 1850s-60s period commercial arm. Mr. Ness' notes indicate that this was made for a US Indian Department trade contract.
