This helmet was probably used by astronaut Wally Schirra during training sessions prior to his Mercury missionin October, 1962.
The helmet was constructed of fiberglass and epoxy resin and was molded to fit directly into the neck ring disconnect. A plastic visor, capable of being raised for access, was attached with pivots, and when lowered into pressure sealing position, it locked in place with a latch. Communication devices with suede-covered ear pads were incorporated into the helmet, and it contained a visor sealing system, ventilation exhaust outlet, and a communications system.
Transferred from NASA - Johnson Space Center in 1977.
