Description
Own a specialized Cold War heavy artillery manual update with this Technical Manual Change 2 for TM 9-1000-217-35P. This change notice covers the 155mm Gun Cannon M46/T80, 8-Inch Howitzer Cannon M47/T89, M86/T58 Gun Mount, and M34/T106 Cannon Firing Mechanism.
This is a Change 2 update for the original TM 9-1000-217-35P, issued May 9, 1962. It is not the full base manual. For collectors, that makes it a valuable companion piece for completing the publication history of this heavy artillery parts manual.
Historical Significance
The original TM 9-1000-217-35P was a Field and Depot Maintenance Repair Parts and Special Tool Lists manual for the 155mm M46/T80 gun cannon, 8-inch M47/T89 howitzer cannon, M86/T58 mount, and M34/T106 firing mechanism.
This equipment family is closely tied to the M53 and M55 self-propelled artillery systems. The M53 carried the 155mm gun, while the M55 carried the 8-inch howitzer. AFV Database notes that the M53 used the same chassis as the M55 and that the M86 mount could accept either ordnance, giving the system important flexibility between the 155mm and 8-inch roles.
That gives this manual change strong collector appeal. It documents the repair-parts side of a major Cold War artillery system, not just the finished vehicle or weapon.
The M46/M47 Cannon and M86 Mount Connection
The 155mm M46/T80 gun cannon and 8-inch M47/T89 howitzer cannon represent two heavy artillery configurations from the same self-propelled family. The M86/T58 mount is the key link between them.
This is the cool factor. The manual change is tied to a system where a common mount supported both heavy cannon roles. That makes it especially interesting for collectors of M53/M55 artillery, Cold War self-propelled guns, and large-caliber U.S. Army ordnance.
The M55 also has strong historical weight. Rock Island Arsenal describes the M55 as a 203mm variant based on the Patton tank, designed to complement and later replace the M53 155mm self-propelled gun. It also notes the vehicle’s armored protection against indirect fire, small arms, and radioactive fallout, reflecting early Cold War battlefield thinking.

Why This Collectible Stands Out
This is not a manual change for a common rifle, truck, or small accessory. It is tied to serious Cold War artillery hardware: 155mm guns, 8-inch howitzers, heavy mounts, and cannon firing mechanisms.
The 35P format adds more collector value. Parts and special-tools manuals show the equipment from a component-level maintenance perspective. They are especially useful for collectors, restorers, museums, and researchers who care about the complete support system behind the weapon.
For collectors of M53/M55 artillery, 8-inch howitzers, 155mm gun systems, or Cold War ordnance manuals, this is a strong reference piece with real technical depth.
