Description
Technical Manual Change 2 (TM 9-1240-258-35P) for M17A1, M17B1C, and M17C Fire Control Range Finders May 1964
This Technical Manual Change 2 for TM 9-1240-258-35P updates the field and depot maintenance repair-parts and special-tools publication for the M17A1, M17B1C, and M17C fire control range finders and is dated May 1964.
The change supplements the original TM 9-1240-258-35P, issued on June 8, 1960. It is a change publication and not the complete base manual.
Historical Significance
The M17-series range finders belonged to the optical and mechanical fire-control systems used on U.S. tanks during the early Cold War, including M48 and M60 applications. These instruments measured target distance and supplied range information for the tank's fire-control process.
Repair-parts publications supported the maintenance system behind this equipment. The May 1964 Change 2 update shows how the Army revised the parts and special-tools reference after the original June 1960 manual entered service.
What This Manual Covers
Change 2 provides dated amendments to TM 9-1240-258-35P, the field and depot maintenance repair-parts and special-tools publication for the M17A1, M17B1C, and M17C fire control range finders. It supplements selected portions of the June 8, 1960 base manual rather than repeating the complete parts list.
The documented range finders measured target distance as part of a tank fire-control system. The manual change concerns maintenance-support information for those instruments, not instructions for operating the range finders.
