Apollo space suit pressure gauge with beta cloth cover layer, measuring approximately 2.5 x 1.5 x 1, which was located on the lower arm so that the astronauts could quickly verify their suit pressure. The top of the blue housing is engraved, “Pt. No. A6L-104025-04, Ser. No. 365, Mfg. by DMD for ILC Industries, Inc.” The beta cloth covering, which protected the gauge from impact and provided thermal protection from solar rays, has a label inside reading, “P/N A7LB-201180-01, S/N DVT 002, Code 74897, ILC Industries, Inc.” In fine condition. This gauge assembly 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 provenance from him. A very seldom seen piece of suit hardware.
