Description
Own a strong piece of Cold War-era Quad .50 machine gun mount documentation with this Technical Manual TM 9-1005-209-34, covering the Multiple Cal. .50 Machine Gun Trailer Mount M55, Multiple Cal. .50 Machine Gun Mount M45D, and Multiple Cal. .50 Machine Gun Mount M45F. This Department of the Army manual is dated May 1958 and was written for field maintenance of these multiple .50 caliber machine gun mount systems.
This is a standout reference for collectors of .50 caliber Browning support equipment, M45 Quadmount systems, M55 trailer mounts, Korean War and Vietnam War ordnance, and U.S. Army technical manuals.
Historical Significance
The M45 Quadmount is one of the most recognizable American multiple-machine-gun mount systems of the 20th century. It was developed from earlier Maxson .50 caliber mounts as the Army sought more mobile anti-aircraft firepower. The Museum of American Armor notes that Maxson expanded the earlier twin .50 mount concept into the four-gun M45 Quadmount, adopted in 1942.
By the postwar period, the system had moved beyond its original anti-aircraft role. It became famous for heavy ground-support fire, convoy security, and base-defense use. That gives this May 1958 manual strong collector appeal. It sits between the Korean War and Vietnam War periods, when the Quad .50 family remained an important part of U.S. military fire-support history.
The M55 is especially collectible because it represents the trailer-mounted Quad .50 configuration. The manual identifies the M55 as composed of the M45C .50 machine gun mount and the M20 machine gun mount trailer, while also covering the M45D and M45F mounts as separate multiple .50 caliber machine gun mount systems.
The M55, M45D, and M45F Quad .50 Connection
The collector “cool factor” is simple: this manual is tied to the Quad .50.
The M55 and M45-series mounts are associated with the intimidating four-gun .50 caliber setup that became famous in multiple conflicts. U.S. Army Center of Military History material describes Vietnam gun trucks equipped with M55 quad .50-caliber machine guns, noting that the M55 used four .50 caliber machine guns operated electronically, with a single gunner firing all four in tandem.
That makes this manual a great reference for anyone interested in:
- M55 Quad .50 trailer mounts
- M45D and M45F multiple machine gun mounts
- Vietnam War gun trucks
- Korean War and Cold War air-defense equipment
- .50 caliber Browning support systems
- U.S. Army field maintenance manuals
- heavy machine gun mount collecting
