Weapon-System Application
The C39 catalog covered the 155mm Howitzer M1 and its M1 and M1A1 carriages, which became part of the later M114 and M114A1 family. This catalog connection supports identifying the item as a flat spring for the M1/M114-family howitzer system. Its exact mounting point has not been verified, so it should not be described as a specific breech, recoil, brake, seat, or carriage spring.
Weapon-System History
The 155mm Howitzer M1 was designed in 1939 and entered production in 1941. It gave the U.S. Army a modern medium artillery piece capable of providing long-range supporting fire. The weapon entered World War II service as the M1 and was later redesignated the M114. Rock Island Arsenal assembled more than 10,000 of these howitzers between 1941 and 1953 and manufactured major carriage and recoil components for the system.
History of Use
The M1/M114 served as a standard U.S. Army 155mm howitzer during World War II, the Korean War, and the Vietnam War. Crews used it to deliver general supporting fire with several types of artillery ammunition at ranges of about nine miles. The M198 began replacing it in U.S. service in 1979, but exported examples continued serving with armed forces around the world.
Package Markings
The marking “8/52 RIA” indicates that the part was packaged or preserved at Rock Island Arsenal in August 1952. This date fits the period when the arsenal was still assembling and supporting the M1/M114 howitzer family. It should be treated as a packaging or preservation date rather than a confirmed manufacturing date for the spring itself.
Condition
This is a vintage military-surplus component that may show storage residue, discoloration, oxidation, scratches, worn finish, or other signs of age and handling. Packaging condition and markings may vary. Please check the pictures for the general condition of the item.
