Technical Manual (TM 9-1240-272-35) for M119 Periscope Mount April 1964 FSN 1240-796-9687
This Technical Manual TM 9-1240-272-35 covers field- and depot-level maintenance for the M119 Periscope Mount, FSN 1240-796-9687, and is dated April 1964.
The M119 supported tank-mounted optical equipment by holding the M32 or M36 periscope within the turret installation. This publication provides a dedicated Army maintenance reference for the mount rather than for the complete vehicle or periscope.
Historical Significance
The M119 Periscope Mount was an important part of U.S. tank sighting and fire-control installations. It supported either the M32 gunner's periscope or M36 commander's periscope, depending on the vehicle arrangement.
The M36 and M119 pairing served in M60-series tank fire-control equipment, while M119 and M119E1 installations also appear in M728 Combat Engineer Vehicle documentation. TM 9-1240-272-35 preserves the maintenance framework used for the original M119 during the 1960s.
M119 Mount with M32 and M36 Periscopes
The M119 mount held and supported the M32 or M36 periscope in the tank turret. Its major functional elements included the mount body, an armored cover, a handle mechanism for opening and closing the protective shield, and headrest assemblies that supported the periscope eyepiece position.
In M60-series applications, the M36 served as the commander's monocular periscope and was mounted in the M119. The periscope connected the commander's sighting line with the tank's machine-gun fire-control arrangement.
What This Manual Covers
TM 9-1240-272-35 is the Army field and depot maintenance manual for the M119 Periscope Mount. Its scope centers on support-level maintenance of the mount and the assemblies that secure, protect, and position the associated periscope.
The publication is distinct from the parts-oriented TM 9-1240-272-35P. It provides maintenance coverage for the original M119 configuration rather than the later combined M119 and M119E1 manual issued in 1983.

Why This Manual Matters
The M119 was a specialized mounting and protective assembly within a larger tank sighting system. A dedicated maintenance manual gives researchers more focused information than a general vehicle manual can provide.
This publication is useful for studying M60-series optics, M728 fire-control components, and the Army's support practices for periscope mounts during the 1960s.
