Description
This M1A2 Carriage Plate for the 155mm M114 Howitzer, identified by FSN 1025-519-1790 and Part Number 5191790, is a specialized military-surplus artillery component associated with the carriage system of the 155mm M114 medium towed howitzer. For collectors of U.S. Army artillery parts, M114 howitzer components, ordnance hardware, restoration reference pieces, and stock-numbered military surplus, this is a focused support item with strong catalog and display value.
Public NSN reference data identifies this item under the modern NSN format 1025-00-519-1790, with NIIN 005191790, item description Plate, and P/N 5191790 associated with the U.S. Army. The same catalog data lists the plate as steel, enamel-finished, and irregularly shaped, with listed dimensional details including 0.125-inch thickness, 2.438-inch longest side, 1.000-inch base width, 1.250-inch top width, two holes measuring 0.281 / 0.297 inch diameter, and two holes measuring 0.203 / 0.219 inch diameter.
The M114 155mm Howitzer and M1A2 Carriage
The 155mm M114 Howitzer belongs to one of the most important U.S. artillery families of the mid-20th century. U.S. Army historical material notes that the M114 traces its history to the 155mm Howitzer M1, first produced in 1941, and later redesignated M114 after World War II. The Army also identifies the M114 as the standard issue 155mm howitzer during both the Korean War and Vietnam War periods.
The carriage system was a major part of the howitzer’s service life. Rock Island Arsenal historical material notes that the M114 was assembled at Rock Island Arsenal from 1941 through 1953, with the carriage and recoil mechanisms produced in-house, and that more than 10,000 howitzers were assembled during that period.
For collectors, that gives this M1A2 Carriage Plate added appeal. It represents the smaller support hardware behind a major artillery system, helping preserve the detailed maintenance, parts, and supply-chain side of U.S. Army field artillery history rather than only the complete howitzer itself.

What This Plate Supports
As an M1A2 Carriage Plate, this item is best understood as a support component associated with a larger artillery carriage assembly. It is not a complete howitzer, not a carriage assembly, not a firing component, not ammunition, and not an explosive item.
In practical collecting and display terms, a component like this is especially relevant for:
- 155mm M114 Howitzer parts collections
- M1A2 carriage component displays
- U.S. Army field artillery restoration reference
- ordnance support and maintenance collections
- military-surplus hardware collections
- museum exhibits on artillery carriage systems
- buyers seeking P/N 5191790 / FSN 1025-519-1790
Because this is a specific part-numbered component, buyers working on a restoration, inventory, or display project should verify fitment against their own parts manual, carriage assembly, and technical documentation before purchase.
Historical and Technical Interest
Small components like this M1A2 Carriage Plate help tell the support story behind the larger 155mm M114 Howitzer system. While the complete artillery piece receives most of the attention, the howitzer’s service life depended on many individual plates, rods, brackets, pins, guards, covers, plugs, and other cataloged parts that allowed the system to be maintained, inspected, repaired, and supported through official supply channels.
For collectors and historians, this carriage plate is especially relevant to subjects such as:
- 155mm M114 Howitzer components
- M1A2 carriage parts
- U.S. Army field artillery support hardware
- World War II and Korean War artillery equipment
- Vietnam War-era artillery support systems
- Rock Island Arsenal artillery production history
Because this is a specific P/N 5191790 Plate rather than a generic surplus item, it adds focused technical depth to collections centered on U.S. artillery, M114 howitzer equipment, carriage systems, and ordnance supply documentation.

Why This Carriage Plate Matters
Many military collectibles focus on complete weapons, vehicles, uniforms, helmets, or technical manuals. This item represents a different but equally important category: the individual components that kept major artillery systems documented, maintained, and supplied.
For collectors, it is a compact and highly specific artillery component with clear FSN and part-number identification. For researchers, it provides a useful example of how small carriage components were cataloged within the military supply system. For museums and displays, it helps show the behind-the-scenes hardware that supported the long service life of the 155mm M114 Howitzer from World War II into the Cold War period.
Because this item is tied to the M114 Howitzer carriage system and carries the traceable identification FSN 1025-519-1790 / P/N 5191790, it is a strong fit for anyone building a focused collection of U.S. field artillery components, M114 howitzer parts, or government-surplus ordnance hardware.
