Exceptionally well-detailed, comprehensive NASA engineer's Lunar Module systems handbook, entitled on the spine, "Lunar Module Systems Handbook, LM-10 and Subsequent Vehicles, Rev. A, PCN-3, Apollo 17, September 30, 1971," prepared by the Manned Spacecraft Center's Flight Control Division, housed in its red 11.5 x 11.25 binder. The handbook consists almost entirely of highly detailed fold-out schematics and diagrams, containing hundreds of pages documenting the LM's structure and systems, including: crew, pyrotechnics, electrical, environmental control, EVA, communications, instrumentation, guidance and control, propulsion, reaction control, and lunar surface equipment. In fine condition, with wear and losses to the clear plastic on the exterior of the binder.
From the estate of NASA engineer Milton J. "Jack" Neubauer, Jr
