Description
USAF MC-3A Pressure Suit &Helmet Rare Clear Face Mask. Exceptional Cold War-era U.S. Air Force high-altitude flight equipment grouping centered around an original Type MC-3A partial-pressure flying suit, complete with associated high-altitude helmet, pressure gloves, breathing equipment, protective covers, flight clothing and accessories. Developed by the David Clark Company during the mid-1950s, the MC-3 series represented a major advancement in partial-pressure protection and was designed to safeguard aircrew operating at extreme altitudes in aircraft such as the U-2, B-47, B-52, B-57, B-58 and F-104, as well as experimental and research aircraft. The MC-3A used inflatable capstan tubes running along the limbs and torso; during a loss of cabin pressure these systems tightened the suit against the body, applying counterpressure and helping sustain the wearer until the aircraft could descend to a survivable altitude. The principal garment is a sage-gray MC-3A high-altitude coverall/partial-pressure suit displaying the characteristic extensive lace-up capstan channels along the arms and legs, multiple adjustment points, zippers and pressure fittings. The surviving nomenclature label identifies the garment as "Coverall, Flying High Altitude, Type MC-3A, " manufactured by the David Clark Company, Incorporated. Of particular importance is the accompanying high-altitude pressure helmet assembly, retaining its off-white rigid shell, period U.S. Air Force wing-and-star insignia, communications equipment, internal padding and neck/pressure garment components. The helmet is accompanied by its breathing hose and an exceptionally scarce transparent pressure face cover/face shield assembly. This clear molded shield incorporates the breathing regulator and fittings directly into the lower portion and is a particularly desirable component because these fragile transparent covers were easily damaged, discarded, separated from helmets or lost after the equipment was withdrawn from service. Far fewer complete transparent face assemblies survive than the helmets themselves, and its presence substantially elevates the historical completeness and display value of this grouping. The clear face cover is personalized "ERVIN, " while the helmet interior is marked "MOHR." Another protective garment carries a handwritten identification panel for "LT. PEKO, " giving the collection multiple period personnel associations. Such mixing of individually marked components is entirely consistent with operational flight equipment that was issued, maintained and reissued through Air Force life-support sections. The ensemble also includes a pair of high-altitude pressure gloves with wrist zippers, leather flying gloves, protective pressure-garment covers, and canvas equipment bags. Condition throughout is service-used and unrestored, with expected age, handling wear, and minor deterioration to certain rubberized and synthetic components consistent with the age of these artifacts. This is an unusually comprehensive Cold War high-altitude grouping, illustrating the remarkable transitional period when military aviation technology was rapidly evolving toward the pressure systems that would ultimately support America’s manned space program.
