50s U.S.A.F. Air Force E-1A Flight Inner Trousers Vintage 28 inch Navy Thank you for viewing. This is a 1950s U.S.A.F. E-1A flight inner pants. Made of wool material, it's warm, and the cuffs are ribbed. There is a faint stain on the left knee that didn't come out in the wash (photo 6). Other than that, I don't think there are any noticeable tears, scratches, or holes. I purchased it at a surplus store near Yokota Air Base in the 80s and have only used it a few times indoors since then. I cannot respond to comments requesting price reductions. Please consider this item with the understanding that it is old. Thank you.
