This pressure helmet was worn by astronaut Donn Eisele during the Apollo 7 mission in October of 1968. Apollo 7 was the first earth orbital flight of the Apollo missions.
The Apollo pressure helmet was a transparent bubble designed to attach to the spacesuit neck ring. It was constructed of a polycarbonate shell with a red anodized aluminum neck ring, a feed port, a vent pad and duct assembly attached to the rear and a valsalva device attached to the inner ring.
There were two configurations used on Apollo suits which were not interchangable, the earlier configuration was anodized blue, with the later configuration being anodized red.
Transferred from NASA in 1982.
