Technical Manual (TM 9-1240-271-35P) for M118 Periscope Mount April 1964 FSN 1240-796-9686
This Technical Manual TM 9-1240-271-35P covers repair-parts information for the M118 Periscope Mount, FSN 1240-796-9686, and is dated April 1964.
The publication serves as the parts-oriented companion to maintenance documentation for the M118. It supports identification and supply research for the mount's service parts and applicable special tools.
Historical Significance
The M118 Periscope Mount provided the mounting interface for the M32 gunner's periscope in U.S. tank fire-control installations. Later Army tank maintenance instructions directed personnel to inspect the M118 when the M32 periscope could not be properly boresighted, showing the practical link between the mount, sight alignment, and fire-control maintenance.
What This Manual Covers
TM 9-1240-271-35P is a repair-parts publication for the M118 Periscope Mount. It is intended to help maintenance and supply personnel identify parts and special-tool requirements associated with support of the mount.
The publication concerns the mount itself rather than operation of the complete tank or the full optical system. It works alongside maintenance instructions by providing the parts-reference side of M118 support.
