I assume this is the first edition as there is no other date or printing listed. The book is in a library binding, and has the original unclipped dust jacket. "Property of the United States Air Force Fuchu Library System" is stamped in the front and in the back. Text appears to be unmarked. One lightly cracked joint, and one illustration page that is loose. Binding and hinges are very good. Many diagrams and lovely vintage photos.
