Signal Corps Technical Manuals, TM-11 Series
Technical Manuals originated ca 1940 as a consolidation of earlier Radio Pamphlets, c 1918; Radio Communications Pamphlets, c 1921; and Training Manuals, Training Regulations, and Technical Regulations, c 1930.
TM 11-201, the earliest known, is entitled "Aircraft Radio SCR-134" and was formerly documented TR-1201-5. Initially, the manuals were not always grouped by equipment category, as the need did not then exist. With the explosion of equipment in World War Two, groupings soon became necessary, as are listed below.
Many of the earlier numbers were "recycled" when the equipment for which they were originally designated became obsolete. There was also an inclusion of early 1950s equipment among much older units. In some cases, an A or B prefix was added to an original number for updating. But in general, a new number would be issued, especially in the latter 1950s. In 1958, a new FSN (Federal Stock Number) procedure was instituted, which more accurately defined the item in question and linked its TM 11- number to its supply number.
