This is a Gemini spacesuit helmet. The David Clark Company made it for NASA. It was likely used for testing, but was never assigned to a specific astronaut. The helmet was constructed of fiberglass and epoxy resin and was molded to fit directly into the neck bearing disconnect. A Plexiglas 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.

NASA transferred this helmet to the museum after the end of the program.
