Description
U.S. 155mm Howitzer M1 Replacement Spring – Drawing A206856
Item Overview
This U.S. military replacement spring was supplied for the 155mm Howitzer M1 system. It is identified by drawing number A206856 and historical Ordnance stock code C39-02-44780. The spring was manufactured by Yuba Manufacturing Company of Benicia, California, U.S.A.
Identification and Features
The official item nomenclature is “SPRING.” Its C39 stock code connects it to the Army’s SNL C-39 supply-catalog family for the 155mm Howitzer M1 and its related equipment. The A206856 drawing number provides the specific design identity needed to distinguish this spring from other components carrying the same general nomenclature.
- Official nomenclature: Spring
- Drawing number: A206856
- Historical stock code: C39-02-44780
- Supply-catalog family: SNL C-39
- Manufacturer: Yuba Manufacturing Company
- Location: Benicia, California, U.S.A.
- Parent system: U.S. 155mm Howitzer M1
How It Worked
This was a passive mechanical component designed to apply spring force within its assigned howitzer assembly. As the connected mechanism moved, the spring was deflected and provided the force needed for the assembly’s designed movement or return action. Drawing A206856 controlled its specific form, load requirements, fit, and installed position within the system.
End-Item/Weapon-System Application
The documented parent equipment is the U.S. 155mm Howitzer M1 system. SNL C-39 covered the M1 and M1A1 howitzers, the M1A1 and M1A2 towed carriages, and the related M14 howitzer mount. The C39-02-44780 stock code places this spring within that artillery supply family, while drawing A206856 provides the correct reference for matching it to its original assembly.
Historical Background
This spring came from the Army Ordnance Department’s organized replacement-parts system for the M1 howitzer family. Components with broad names such as “SPRING” were assigned individual drawings and stock codes so the correct replacement could be manufactured, stored, and issued for maintenance. Drawing A206856 identified this component’s design, while C39-02-44780 connected it to the applicable howitzer catalog. The Yuba Manufacturing Company identification documents a commercial manufacturer that supplied parts for the Army artillery program.
Equipment/Weapon-System History
The 155mm Howitzer M1 was designed in 1939 and entered production in 1941. It was a medium towed artillery weapon developed for the modern, motorized U.S. Army and became an important field-artillery system during World War II. Rock Island Arsenal assembled more than 10,000 examples between 1941 and 1953. The weapon was later redesignated as the M114 and remained in American service until the M198 began replacing it in 1979.
History of Use
The M1 served U.S. artillery units during World War II and continued as the standard American 155mm towed howitzer during the Korean and Vietnam Wars. Crews used it to provide general supporting fire for infantry and armored forces. It fired separate-loading ammunition, with the projectile and selected propelling charge loaded as separate components, and could reach targets approximately nine miles away. Cataloged replacement parts such as this spring supported the inspection, repair, and continued maintenance of the weapon system throughout its long service life.
