Apollo 15 Lunar Module Range/Rate Indicator gauge, mounted in clear Lucite, measuring approximately 4 x 5 x 6, and weighing 3.75 pounds. This unique gauge was removed from the M-6 test vehicle, a full-scale mock-up of the Lunar Module interior as the result of the Apollo 15 LM crew finding the outer pane of glass on the Lunar Module Falcon Range/Rate Indicator gauge broken. This unit was similarly broken during the Apollo 15 flight for flammability testing to see if the presence of oxygen in the electrical circuitry of this gauge posed any fire risk to the Lunar Module Falcon. The Flammability Test Report concluded ‘the presence of oxygen in the unit created no flammability constraint to the continuation of the Apollo 15 mission.’ Signed on the Plexiglas cover of the gauge in silver ink, “Dave Scott, Apollo 15 CDR, Falcon Endeavor.” In very good condition, with cracked and chipped outer pane and expected scorching and distress from testing. Accompanied by seven color NASA ‘red-numbered’ photos of the gauge in various stages of the test, a certificate of authenticity from Novaspace for Scott’s signature, and a CD with 47 images of the gauge, Scott signing the gauge, and the NASA testing report. A unique piece of equipment and documentation. Provenance: Goldberg Auction 2008. Pre-certified Steve Zarelli and RR Auction COA.
