Description
Own a specialized piece of Cold War / Vietnam War-era U.S. Army ordnance documentation with this Technical Manual Change 3 for TM 9-1000-202-35, covering Evaluation of Cannon Tubes. Dated September 1965, this change notice updates the original TM 9-1000-202-35 issued March 27, 1964.
This is not a general weapons manual. It deals with one of the most important technical subjects in artillery and tank-gun maintenance: determining the condition of a cannon tube. For serious ordnance collectors, that gives this piece strong appeal. It documents the inspection side of major weapon systems, where safety, accuracy, service life, and readiness all came together.
Historical Significance
The TM 9-1000-202-35 manual family was created for ordnance personnel responsible for judging cannon tubes. Earlier Army manual text describes the series as covering the latest information for evaluating cannon tubes, operating bore inspection devices, and using velocity-measuring equipment.
That makes this September 1965 Change 3 an interesting Cold War update. By 1965, the U.S. Army was operating a wide range of cannon-armed systems, including tanks, towed guns, howitzers, recoilless rifles, and self-propelled artillery. Tube condition mattered across all of them.
A worn or damaged cannon tube was not just a maintenance issue. It affected accuracy, safety, and the useful life of the weapon. This change notice belongs to the technical paperwork system that helped keep those systems inspected, evaluated, and documented.
What This Change Covers
As Change 3 for TM 9-1000-202-35, this publication updated the Army’s technical manual for Evaluation of Cannon Tubes.
The manual family covered subjects such as:
- types of erosion and damage
- plated and non-plated bore wear
- manufacturing defects
- coppering, rust, scoring, and constrictions
- deformation of rifling lands
- heat checks and progressive stress damage
- visual inspection
- gage inspection
- borescope use
- pullover gage reference
- remaining tube life estimation
- condemnation criteria
- cannon tube calibration
The listed contents of the manual family include chapters on types of erosion and damage, inspection, evaluation of cannon tubes, and calibration of cannon tubes.

Why This Collectible Stands Out
Most military manuals cover a specific weapon, vehicle, or piece of equipment. This one is different. It covers the condition of the cannon tube itself.
That gives it real collector value. It is the kind of manual that explains the hidden technical world behind artillery and tank-gun readiness. It pairs well with manuals for 90mm guns, 105mm tank guns, 155mm howitzers, 8-inch artillery, recoilless rifles, and Cold War ordnance systems.
Manual changes are also important to collectors because they show the living history of a technical publication. The base manual was not static. It was updated as procedures, references, and equipment support requirements changed. This Change 3 update is part of that revision history.
