Early brad-bound softcover handbook entitled "Saturn S-IVB Training Graphics," prepared by the Missile & Space Systems Division of the Douglas Aircraft Company, 8.75 x 11.25, dated September 1963. Labeled "For Training Use Only," the book consists almost entirely of simplified diagrams, drawings, and schematics documenting the Saturn S-IVB (third stage on the Saturn V launch vehicle), organized into tabs for the various systems and subsystems: "Structures," "Manufacturing," "Electrical," "Hydraulics," "J-2 Propulsion," "Propellant Utilization," "Auxiliary Propulsion," "Ordnance, " "Instr. & Telemetry," "Automatic GSE," "General GSE," and "Countdown & Mission." The "J-2 Propulsion" section is empty, with a single page noting that the material is "Classified Confidential." In very good to fine condition, with wear to the tabs and moderate creasing to the covers.
