Apollo space suit internal electrical connector with battery pack and signal conditioner mock-up, featuring a weighted two-inch square wooden block to simulate the battery and signal conditioner unit, attached to a wiring harness with blue anodized disconnect made by Air-Lock. In very good condition, with some wear and soiling. This harness has been authenticated by Bill Ayrey, company historian at ILC Dover, the manufacturer of the Apollo, Shuttle, and Space Station suits, and is accompanied by a letter of authenticity. A rare, interesting Apollo suit artifact.
