Counterpane with a weak, incorrect script ESA cartouche. Bridesburg marked rifle muskets were primarily produced by Alfred Jenks & Co of Bridesburg and Philadelphia, PA, although Jenks also delivered component parts to other contractors and Bridesburg marked locks are found on guns made by James T Hodge as well. Jenks received multiple rifle musket contracts, primarily for the M1861 pattern guns, but his last deliveries were of the M1863 pattern with the flat faceted hammer, flat bolster, convex screw tensioned barrel bands and straight shank ramrod typical of those guns. It is believed that all 6,000 of the guns he delivered in 1865 were of that pattern, and likely his later deliveries during 1864 as well. {ANTIQUE}
