Rare Space Shuttle Main Engine Design Features Overview Manual Rockwell NASA For Sale

Original vintage Rockwell NASA space shuttle main engine overview document, details the parts of the shuttle's main engine with a diagram and description of each part, from the estate of a longtime NASA engineer. Looks like it dates from before the first shuttle launch. Shows age, wear and tear, handling wear, storage wear, lots of bug damage to front and back covers and some page edges, but the pages look great overall, see photos for details, message me with any questions.
