Navigators Information File, WWII C-130 Here is a WW2-era BritishThis is an original WWII era Navigators Information File published in 1944 (updated 1945) 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. It is in very good condition given its age.
