Early Apollo Command Module (Block I) armrest attachment, measuring approximately 13 x 4, with locking and unlocking hand control attachment and armrest adjustment. Label on metal armrest pad reads, “VI6–53I765, S/N0. 6362PAA2850, Unit A. V. T., 32I–67–0I0, SNM 460,” with underside reading, “V36–531770 Assem., 6–Dec–67, ANA 657.” Bottom portion of extension tubing bears an affixed printed label, “993 2SP00, 312,” and toned tape remnants with a felt tip notation, “#75.” The Apollo Command Module Block I armrest mounted to the crew couch and provided an attachment point for the translation and rotational controllers.

An intriguing piece of hardware from the Apollo Block I capsule, predecessor parts which remain far less common the Block II examples which followed.
