This official 1917 instruction booklet on aerial gunnery aims to give the novice Great War gunner a complete picture of his work. There is a great emphasis - with diagrams and photographs - on the use of the RIng Back-Sight and the Wind-Vane Foresight (Norman Pattern) as well as the Aldis Optical Sight. For training purposes there are instructions for the use of a model aiming aeroplane to target; the use of tracer and ordinary Mark VII ammunition; and instructions for using the Hythe Gun camera, as well as shooting practice at a picture target. A must read for all aerial warfare fans.
