This Technical Manual Change 1 for TM 9-1240-258-35P updates the parts publication for the M17A1, M17B1C, and M17C Fire Control Range Finders and is dated February 1963. It applies to the original technical manual issued on June 8, 1960.
Change 1 is a separate update notice intended for use with the base manual. It does not contain the complete original publication.
Historical Significance
The M17-series instruments were optical fire-control range finders associated with M60-era 105 mm gun tanks. They helped crews determine target range, an essential value for accurate direct fire.
The original 1960 parts publication supported maintenance of this specialized fire-control equipment. This 1963 change notice reflects the Army's continuing work to keep its repair-parts documentation current.
What This Manual Covers
Change 1 provides the February 1963 update to the repair-parts publication for the M17A1, M17B1C, and M17C Fire Control Range Finders. The base -35P manual serves as a field and depot maintenance repair-parts and special-tools reference.
The notice is valuable for maintaining a period-correct reference set and understanding the official revision history of the publication.
