An Original WW2 M-1 Fixed Bale helmet shell.
The condition of the McCord shell is fantastic, the paintwork and cork are both very good and no stress cracks are present.
At some stage the helmet has been adapted for Air Force use as the chinstraps have been cut off, the bales have been cut in the middle and a leather chin cup has been added. This would allow the helmet to be worn over a flying cap. I suspect this has been done post WW2.
But if you add some original WW2 OD-3 chinstraps this would make a great Fixed bale shell.
