This is an exceptionally rare Mine Safety Appliances manufactured helmet liner. M.S.A. received the very first contract for high pressure helmet liners on February 4, 1942. The contract at the time was for only 12,000 liners, compared to the 1,000,000 for both Inland and Westinghouse. This is one of M.S.A.'s earliest-produced helmet liners. It features parkerized steel A-washers and a first pattern rayon suspension, dating the liner's production to mid-1942. The strong and intact Johnson & Johnson manufactured rayon suspension is ID'd to Gustaf E. Berglund, serial number 35877990. Berglund enlisted in Cincinnati, Ohio on October 13, 1943. View the Veteran's Information section to see Berglund's National Archives Service Record - a copy of which will be provided to the new owner. The suspension comes complete with its original khaki neckband, bearing Berglund's laundry number, as well as a recently installed original size 7 1/8 rayon headband. The liner's exterior has been stripped of its paint finish.
