Two used Apollo Communications Control Unit Assembly adapters. Each adapter measures 16.5″ long, with a male connector at one end, a female connector at the opposite end, and a microphone plug located in the center. Each is wrapped in red tape and beta cloth, with one labeled “Ground Test Only.” In very good condition, with moderate wear to coverings of both and some old tape around one microphone connector. These style connectors would have been part of the astronaut’s constant wear garment communications harness. RR Auction COA.
