This is an experimental Apollo helmet, with a gold neck ring instead of the blue or red used on the Apollo missions. It's use history is unknown.
The Apollo pressure helmet was a transparent bubble designed to attach to the spacesuit neck ring, and its size and shape enabled the astronaut to move his head within it. The helmet was constructed of a polycarbonate shell with an anodized aluminum connector ring that attached directly to the matching neck ring on the spacesuit. It was equipped with a feed port, a vent pad and duct assembly attached to the rear and a valsalva device attached to the inner ring.
Transferred from NASA in 1982
