This pressure helmet was worn by astronaut Pete Conrad, Commander of the Apollo 12 mission in November, 1969.
The Apollo pressure helmet was a molded, polycarbonate bubble with an anodized aluminum neck ring that locked into place with the corresponding neck ring of the spacesuit. There were two neck ring configurations used on Apollo suits which were not interchangable, the earlier version was anodized blue, with the later being anodized red.
