Technical Manual (TM 9-1240-273-35P) for M145/T208 Telescope Mount April 1970 FSN 1240-871-2969
This Technical Manual TM 9-1240-273-35P covers repair-parts and special-tools information for the M145/T208 Telescope Mount, FSN 1240-871-2969, and is dated April 1970.
The M145 mount supported the M117 panoramic telescope in self-propelled howitzer fire-control installations. This parts publication complements the maintenance instructions for the mount with component and supply-reference information.
Historical Significance
The M145/T208 mount belonged to the fire-control equipment developed for the M108 105 mm and M109 155 mm self-propelled howitzers. With the M117 panoramic telescope installed, the sighting assembly allowed the weapon to be laid in azimuth for indirect fire.
The M145 provided an adjustable base that helped keep the panoramic telescope's vertical axis plumb when the vehicle was pitched or canted. This supported useful weapon azimuth and elevation readings from a mobile artillery platform.
M145 Mount with the M117 Panoramic Telescope
The M145 held and supported the M117 panoramic telescope at the gunner's position. The mount was installed in the vehicle cab near the weapon breech and provided the adjustable interface between the telescope and howitzer fire-control system.
In this arrangement, the M117 supplied azimuth measurements while the M145 mount contributed weapon-elevation information and leveling adjustment. Together they supported indirect-fire laying of the M108 and M109 self-propelled howitzers.
What This Manual Covers
TM 9-1240-273-35P is the repair-parts and special-tools publication for the M145/T208 Telescope Mount. It supports parts identification and supply research for maintenance of the mount.
The manual concerns the telescope mount rather than operation of the complete howitzer or the M117 optical instrument. Its parts focus complements the separate maintenance instructions for the T208/M145 mount.

Why This Manual Matters
Parts manuals preserve component and supply information that broader vehicle publications may not provide. This manual gives collectors and researchers a focused reference for the mount that connected the M117 panoramic telescope to the howitzer fire-control system.
It is especially useful for technical libraries centered on M108 or M109 artillery, indirect-fire sighting equipment, and U.S. Army optical maintenance support.
About This Manual
This Department of the Army publication is TM 9-1240-273-35P, dated April 1970. It documents repair-parts support for the M145/T208 Telescope Mount under FSN 1240-871-2969, later formatted as NSN 1240-00-871-2969.
Later Army documentation continued to identify the M145 mount and its M117 panoramic telescope relationship within the M109-series fire-control system.
