Description
Own a solid piece of Cold War field artillery history with this Technical Manual Change 2 for TM 9-331A, covering the 155mm Howitzer M1 and 155mm Howitzer Carriages M1A1 and M1A2. Dated February 1961, this change notice is tied to one of the most important U.S. medium artillery systems of the 20th century.
This is not the full base manual. It is a Change 2 update for the TM 9-331A manual family. The base TM 9-331A is documented as a Department of the Army technical manual for the 155-mm Howitzer M1 and 155-mm Howitzer Carriages M1A1 and M1A2, dated January 1953.
Historical Significance
The 155mm M1 Howitzer later became known as the M114, one of the longest-serving American artillery systems ever produced. U.S. Army history notes that the M114 was first designed in 1939, produced in 1941, entered service during World War II as the M1, and was later redesignated M114 after an Army numbering-system reorganization. It was also standard issue during both the Korean War and Vietnam War.
That gives this February 1961 Change 2 strong collector appeal. It represents the continued technical support of a proven World War II and Korean War artillery system during the Cold War. By 1961, the M1/M114 family was still an important part of U.S. artillery history, training, maintenance, and field documentation.
A February 1961 Army field manual for the 155-mm Howitzer, M1 Towed also references TM 9-331A, showing that this manual family remained part of the working artillery documentation system during the same period.
What This Change Covers
As Change 2 for TM 9-331A, this publication updated the technical manual for the 155mm Howitzer M1 and the M1A1 / M1A2 howitzer carriages.
A change notice like this is especially relevant for:
- TM 9-331A revision history
- 155mm M1 / M114 howitzer documentation
- M1A1 and M1A2 carriage reference
- Cold War artillery maintenance research
- U.S. Army technical manual collections
- museum and archival reference libraries
- collectors completing a TM 9-331A manual set
Manual changes are often harder to find than base manuals. They were working updates, meant to be inserted, retained, or referenced with the original publication. That makes surviving examples valuable to collectors who care about the complete publication history.

Why This Collectible Stands Out
The 155mm M1 / M114 howitzer has real collector weight. It served across major 20th-century conflicts and became one of the classic American medium howitzers.
This Change 2 update adds another layer of interest. It shows that the Army was still maintaining and updating the official documentation years after the original 1953 manual. For collectors, that makes it more than a loose paper update. It is part of the long service story of a major U.S. artillery system.
This is a great addition to a technical manual library, especially if your collection includes 155mm artillery, M114 howitzer items, Korean War manuals, Cold War ordnance publications, or U.S. Army field artillery documentation.
