This 155mm M1 "Long Tom" Gun Axle Housing is an original U.S. military artillery component, part of the split-trail carriage system that supported the M1 and M2 towed field gun. Identified by Part Number 7115314 and FSN 1025-00-711-5314, this axle housing was a critical structural element of the Long Tom's M1A1 carriage, designed to handle the immense recoil and transport demands of this powerful long-range field artillery piece.

Developed during the interwar period and deployed extensively in World War II and Korea, the 155mm M1 Gun—commonly known as the "Long Tom"—was the backbone of U.S. heavy artillery. It fired 155mm shells over distances up to 25,000 yards with remarkable accuracy and was renowned for its reliability and destructive power. The split-trail M1A1 carriage featured a heavy-duty axle system capable of supporting this weapon in both firing and towed positions, often behind a Mack NO or M4 High-Speed Tractor.

This original axle housing is ideal for restoration projects, historical vehicle collectors, or museums preserving America's WWII artillery legacy. The item may show storage wear consistent with age.
