Wendt’s unbound Pad 39B White Room checklist manual used during the Apollo-Soyuz mission, approximately thirty double-sided sheets, 8.5 x 11, signed on the reverse of the first page in black ballpoint, “My actual ASTP countdown preparations-launch operations checklist, Guenter F. Wendt, AS-210 Padleader.” The manual is copiously annotated throughout by Wendt, with various items underlined and checked off, times written down, and directions noted, such as, “Make tape strips & bags for hose fittings,” “Start hatch inspection,” and “Remove helmet protectors.” In very good condition, with expected wear from mission use. A superb personal piece from an essential member of the ground team. The Guenter Wendt Collection, ex. Ken Havekotte. Pre-certified Zarelli Space Authentication.
