Blue anodized Apollo space suit ventilation manifold manufactured by Airlock, measuring approximately 5 x 3.25 x .75, consisting of three separate components identified as “PN-2134, SN-241,” “PN-2389B, SN-298,” and “PN-1925, SN-447.” All are also etched, “Class III.” The manifold was used inside of the Apollo space suit to provide the proper oxygen flows throughout the suit. This unit would have had a diverter valve that the astronaut would rotate to provide either 12 cubic feet of air-flow to the helmet and the lower extremities or 6 cubic feet just to the helmet as when on the lunar surface. In fine condition. This hardware 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 provenance from him.
