A valuable U.S. Air Force flight helmet from the Vietnam War era (1971). Size: Regular It was in its original box when released, but the box and the inner sponge have deteriorated and are crumbling due to aging. There are no scratches or signs of use on the helmet itself. Please check the photos and understand that this is a used item before purchasing, as it has been stored for a long time. I have other items for sale too! #makoメンズ服断捨離中 (mako men's clothing decluttering)
