This TM 3-1040-244-12 Compressor, Reciprocating, Power-Driven, Flame Thrower 3-1/2 CFM, AN-M4/C Technical Manual Change 2 Dated: 1966, is a Cold War-era U.S. military technical manual update for the Compressor, Reciprocating, Power-Driven, Flame Thrower, 3-1/2 CFM, AN-M4/C, also identified as Stewart-Warner Model 3260101-6. This change was issued specifically for the TM 3-1040-244-12 technical manual printed December 13, 1965, making it an important companion document for collectors, researchers, restorers, and anyone building a serious reference library around U.S. military flame-thrower support equipment and Army technical literature.
Unlike a full base manual, this item is an official Change 2 publication. That means it was issued to revise and update the original manual rather than replace it outright. For collectors, that matters. Military manuals were routinely kept current through numbered changes, and surviving change issues help document how technical guidance, maintenance information, and service procedures evolved while the equipment remained in use. In that sense, this is not just an update sheet. It is part of the actual service history of the manual itself.
The AN-M4/C Compressor
The AN-M4/C compressor belongs to the support-equipment side of U.S. military flame-thrower systems. Identified here as a reciprocating, power-driven compressor rated at 3-1/2 CFM, and tied to Stewart-Warner Model 3260101-6, it represents the kind of specialized service equipment that supported military flame systems rather than the weapon assemblies themselves. For collectors, that makes this manual especially interesting because it documents the less-visible logistical and maintenance side of flame-thrower operations.
Support equipment manuals like this are often harder to find than the manuals for the main end item. They also add depth to a collection by showing how the U.S. military handled the inspection, servicing, and upkeep of specialized supporting hardware.
What This Manual Change Covers
As a technical manual change, TM 3-1040-244-12 Change 2 would have been issued to revise and update the information contained in the original December 13, 1965 printing of the manual.
In practical terms, publications like this are especially relevant for:
- updated technical guidance
- revised maintenance or servicing information
- corrected procedures or data
- manual-issue history and documentation
- restoration and archival reference
- collecting complete sets of original military manual changes
Because it is a Change 2 issue, it is especially useful for collectors who want to pair it with the original base manual and preserve the manual as it was actually updated and used in service.
Historical Significance
The date 1966 places this publication in the Cold War period, when the U.S. military was still maintaining specialized flame-thrower systems and the technical literature that supported them. That gives this change added historical value because it reflects the continued service life of support equipment associated with military flame systems and the Army’s effort to keep its documentation current.
For collectors and historians, this manual change is especially relevant to subjects such as:
- Cold War U.S. Army technical manuals
- military flame-thrower support equipment
- specialized compressor and servicing systems
- combat engineer and special-weapon support history
- dated military paperwork and manual changes
Because it is a change issue, it also appeals to collectors who appreciate the way military manuals were actually maintained in service rather than preserved only as first-print base editions.
About This Item
This listing is for TM 3-1040-244-12 Compressor, Reciprocating, Power-Driven, Flame Thrower 3-1/2 CFM, AN-M4/C Technical Manual Change 2 Dated: 1966. It was issued for the December 13, 1965 print of the original TM 3-1040-244-12 manual.

Why This Manual Matters
Many military manuals focus on the weapon itself. This one is important because it documents the support and maintenance side of a specialized military system. It helps show how the Army handled the technical upkeep of equipment associated with flame-thrower service and support, which adds a different layer of historical value than an operator-only or end-item-only manual.
For collectors, it is a useful companion piece to the original 1965 TM 3-1040-244-12. For restorers and researchers, it helps document the continued maintenance history of the AN-M4/C compressor system. For museums, it adds context to the administrative and technical side of military support equipment that is often overlooked.
