My own bet w/ the partial signature especially is
Ford, John (1780-1862). gun- and silversmith. 1839, corner of Front and Walnut Sts.; 1842, Front and Locust Sts., Harrisburg [tax; Census; Harrisburg Dirs.]. John was born on 5 January 1780, a son of Peter and Rebecca [Shipe] Ford of York. In 1801 he moved to Harrisburg. In 1803 he married Mary Schnevely [1781-1830]. He made a gun that was once in the State Museum in Harris¬burg. In 1807 the Commonwealth paid Ford $704.12 for making repairs to state militia arms. He died on 31 January 1862 [Egle, Dauphin and Lebanon Counties, pp. 492-93; 2 Hazard's Annals 59]. Ford John, gunsmith, n. Front, bel Locust st [1845 dir.].
I photographed 2 signed guns w/ essentially the same patchbox.
