Irwin’s personal off-white ‘TOPTEX’ flight helmet bearing metal tags on each earpiece reading, “N 383-85782A, Columbus Milpar & Mfg. Co. Inc., Part No. 60C445,” with an “Irwin” decal affixed to the back. Helmet is lined with padded leather, and has a retractable visor with dark lenses and a dark green oxygen mask manufactured by Sierra, with a communications cable running along the air tube. Includes the original dark green cloth bag, which bears a NASA logo patch. In fine condition. Accompanied by a certificate of authenticity from Irwin’s son, James B. Irwin II. This helmet would have been flown in a T-38 to train a pilot for supersonic flight and these models were used widely during the 60's by USAF and USN aviators. A unique personal item as T-38s were routinely flown by NASA astronauts to maintain pilot proficiency. RR Auction COA.
