Most of the estimated prices seem WAY low to me.
This one, Lot #77, brought me a smile:
Bill, tgo
Grateful Dead
Army surplus aspirator repurposed for nitrous oxide by the Grateful Dead, ca. 1974
Aluminum and plastic case (19.5 x 24 x 8’’) with Mine Safety Appliances aspirator in lower compartment, including mask, valve, meters, and nitrous oxide modification. “MSA | Pneolator” printed on upper lid; case scratched and worn from road-use.
While the MSA Pneolator was originally an aspirator featuring “infant,” “child,” and “adult” settings, the Grateful Dead repurposed it for their own ends, modifying it to deliver doses of nitrous oxide.
“Big” Steve Parish: “Bought by us on the crew while buying Army surplus racks for the Wall of Sound. Used for nitrous oxide—one of our fun party favorites. We used it for recreation at all private parties and at many shows, as seen in The Grateful Dead Movie. This oxygen mask was a convenient way to solve the problem of a direct delivery system, providing a reliable connection to pass around a hose attached to the nitrous tank. Provided an easy way for the band and crew to have a quick hit at the show.”
