Description
Own a serious piece of Cold War heavy artillery documentation with this Technical Manual TM 9-1000-218-35, covering the 175mm Gun Cannon M113 / T256E3, 8-Inch Howitzer Cannon M2A1E1, M158 / T185 Mount, and related loader and rammer equipment. This manual is dated August 1962, with reference listings identifying the publication date as August 20, 1962.
This is a Field and Depot Maintenance Manual, making it a deeper technical reference than a basic operator’s guide. It is tied to the early service period of the M107 175mm Self-Propelled Gun and the M110 8-Inch Self-Propelled Howitzer, two of the most impressive U.S. heavy artillery systems of the Cold War.
Historical Significance
The M107 and M110 represented a new generation of large self-propelled artillery. They were built around a common chassis concept, with the M107 carrying the long-range 175mm gun and the M110 carrying the heavy 8-inch howitzer. Reference material notes that the M107 and M110 shared the same low hull, weapon mounts, loading and ramming devices, and rear stabilizing spade.
That gives this manual excellent collector appeal. It documents the gun, howitzer, mount, loader, and rammer side of a heavy artillery family that bridged early Cold War development and Vietnam War service.
The M107 175mm gun became famous for long-range fire support. The M107 was used extensively in Vietnam, could fire more than 30 km, and took part in cross-DMZ artillery duels. The M110 8-inch howitzer brought a different kind of power, firing a 200-pound projectile to almost 16,800 meters.
The M113 Gun, M2A1E1 Howitzer, and M158 Mount
This manual’s subject matter has real “big gun” appeal. The 175mm M113 / T256E3 gun cannon was the heart of the M107 system. The 8-inch M2A1E1 howitzer cannon connected the same general mount family to the M110. The M158 / T185 mount tied both systems to the heavy recoil, alignment, and support structure needed for large-caliber self-propelled artillery.
AFV Database references the manual as covering the 175-mm Gun Cannon M113 (T256E3), 8-inch Howitzer Cannon M2A1E1, Mount M158 (T185), and Loader and Rammer.
For collectors, this is the cool factor. This manual is not about a small accessory. It covers the field and depot maintenance side of two massive artillery systems and the hardware that made them work.
What This Manual Covers
As TM 9-1000-218-35, this manual would have served as an official Army field and depot maintenance reference for the heavy cannon, howitzer, mount, loader, and rammer equipment.
This manual is especially relevant for:
- 175mm M113 / T256E3 gun cannon documentation
- 8-Inch M2A1E1 howitzer cannon reference
- M158 / T185 mount research
- loader and rammer system documentation
- M107 and M110 self-propelled artillery collections
- Cold War and Vietnam War artillery displays
- field and depot maintenance manual libraries
- museum and archival reference collections
The M158 mount itself is a major technical subject. AFV Database describes it as a hydropneumatic, variable-recoil mount with a cradle supporting the gun during recoil and counterrecoil, along with recuperator, replenisher, and variable recoil components.

Why This Collectible Stands Out
This manual stands out because it covers heavy artillery at the component-support level. It is not just a broad overview of a vehicle. It documents the cannon, howitzer, mount, loader, and rammer systems behind two major self-propelled artillery platforms.
The M107 and M110 have strong collector appeal because they were large, powerful, and unmistakably Cold War. They belong to the era of long-range artillery, Vietnam War fire bases, heavy tracked guns, and specialized maintenance support.
For collectors of M107, M110, 175mm artillery, 8-inch howitzers, or Cold War ordnance manuals, this is a strong technical reference with real display and research value.
