Original U S Govenment RESTRICTED instruction manual for aerial gunners. Publised with help of Time Inc November 1 1943, right in the middle of WW II when our bomber losses were staggering. A great tribuite to the men of the Mighty 8th Air Force in England or the 15th Air Force in Italy who took the fight to Germanyin their B-17's and B-24's and paid a heavy price for doing so.
