Two mid-19th century gunmakers named Gibbs worked in Lancaster, PA. Abraham Gibbs is listed by Sellers as circa 1857. Henry Gibbs (1824-1880) is listed as worked circa 1857-1870. Sellers notes that Henry made particularly high quality guns. The fit and finish of this trade rifle is superior to many and may be the work of Henry Gibbs, although Mr. Ness' notes indicate he felt this gun was made by Abraham.
