Description
Technical Manual Change 1 (TM 9-1240-262-34) for M105, M105C, M105D, and M105F Articulated Telescopes June 1965 FSN 1240-764-1667
This Technical Manual Change 1 for TM 9-1240-262-34 updates the field-maintenance publication for the M105, M105C, M105D, and M105F articulated telescopes, and is dated June 1965.
The physical publication is the Change 1 notice only. It applies to the original TM 9-1240-262-34 dated January 31, 1963, and is not the complete base manual.
Historical Significance
The original January 1963 manual covered the M105, M105C, and M105D articulated telescopes. Change 1 expanded the listed model coverage to include the M105F, recording the development of the telescope family as it served additional armored-vehicle fire-control applications.
These telescopes formed part of secondary direct-fire systems. Their design let the objective follow gun elevation while keeping movement at the gunner's eyepiece relatively limited.
Change 1 and Expanded M105-Series Coverage
The M105 was intended for the secondary direct-fire system of the M48-series 90 mm gun tank. The M105C and M105D served the corresponding system on the M60 and M60A1 105 mm gun tanks.
The M105F supported direct fire for the 165 mm gun in the T118E1 Combat Engineer Vehicle, later standardized as the M728. Adding this model connected the manual series with a specialized armored-engineer application.
The telescope family used an 8-power optical system with a 7.5-degree field of view and two selectable ballistic reticles calibrated for range in meters.
What This Manual Covers
Change 1 supplies the June 1965 revisions to the field-maintenance guidance in TM 9-1240-262-34. Its model line covers the M105, M105C, M105D, and M105F articulated telescopes.
The notice updates an existing maintenance publication. It is not a crew-level operator's guide, a parts-only manual, or a stand-alone replacement for the complete January 1963 base manual.
