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 like this one. Jenks was the most successful of M1861 contractors, delivering more than 92,000 rifle muskets between 1862 and 1865. Some 20,000 guns more than his next closest competitor, the Providence Tool Company, who delivered 70,000 guns. {ANTIQUE}
