An Apollo A7L Spacesuit EVA Emergency Oxygen Pack, complete with oxygen bottle. Pack has a contoured back for easier fit, and measures approximately 8.5 x 15, weighs approximately 14 pounds, and is stenciled “AEE Air Supply.” Top has a metered gauge along with the important operating instructions, which read, “1. Neck trap on. 2. Connectors in hard! A. Red to Red B. Blue to Blue. 3. Air supply one. 4. Suit diverter valve vertical.” Front has red and blue valves, as well as the red valve to turn on the oxygen. The heavy duty reinforced neck strap is also present. In fine condition, with scattered dings and soiling.
This flight-ready pack would have been used during Skylab EVAs. During spacewalks on Skylab, designed to be of short duration, the Apollo backpack was replaced with a dual purpose umbilical chord, which supplied both oxygen and water for cooling. This pack would have been strapped to an astronauts thigh and was able to provide 30 minutes of pure oxygen in case of an umbilical failure. A very interesting and visually appealing item, one of the more crucial pieces for a spacewalk. RRAuction COA.
