This collection consists of two aviation technical manuals. The first is a service manual for hydromatic quick-feathering propellers, models 23E50-31 and above, and the second manual is a Gunner's Information File on flexible gunnery, Air Force Manual No. 20.
Manufacturers and operators of aircraft and equipment produce large numbers of manuals for their air and ground crews. These manuals generally cover all phases of operation, from assembling the newly-purchased aircraft, operation and maintenance of the equipment, to storage of the equipment. Manuals are updated (revised) as new procedures are developed or modifications are made to existing models. New subtypes generally receive new manuals, although subtypes with the same procedures are generally grouped into the same manual, with new models being added in revisions.
