Navigators Information File, Sept 1944 WWII Grumman with the pointer rotating onceThis is an original WWII era Navigators Information File published in 1944 (updated Sept 1944) by the US Army Air Force. It is the basic reference book for aircraft navigators in the performance of their duties. See photos. The page numbers are by section, so total pages are not estimated here. It is about 1 2 inch thick. All pages are intact as is the soft cover, which has some wearmarks. It is in very good condition given its age.
