Interesting group of blueprints related to the Saturn S-IVB and its umbilical assembly, including: a 36 x 24 blueprint entitled "Model SIV-B Umbilical Disconnect Mock-Up—Mechanical"; a 34 x 25.5 blueprint entitled "Layout—Swing Arm & Umbilicals, C-5 Vehicle, Incorporating Automatic Reconnect of LH2 & Gas Lines"; and a two-sheet 36.5 x 33 layout blueprint of the checkout area and transfer dolly. In very good to fine condition, with heavy toning to intersecting folds.
