This pressure helmet is the replacement made by NASA for the one worn by Jack Lousma for the second manned Skylab mission in July, 1973.This helmet is identical to the flown mission helmet, which 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 to the National Air and Space Museum by NASA in 1976.
