Fighter Pilot Gunnery, How to Make Your Bullets HIT, TO NO 00-25-35

This original WWII-era booklet Fighter Pilot Gunnery, published December 1943, was used to train fighter pilots on the tactics of fixed gunnery when pursuing enemy aircraft. 

This 27-page guide instructed pilots on use of the gunsight, lead and deflection, approach angle, and provides target lead and range tables for German and Japanese aircraft common in 1943.

This guide is in reasonable condition for its age. There are pencil markings on the cover, but all of the pages are present in intact.
