Very good condition for age. Two pages have a few spots and light pencil marks. Does not affect text.  All other pages are clean and unmarked. No missing, bent, or torn pages.  Previous owner book stamp neatly on front end-page corner.  "Missile" stamped on book edges and inside covers (likely came from either a Naval Station San Diego or USS Norton Sound technical library). From a family collection. Please see photos for additional details.
