WW2 USSAF Type A-5 Intermediate Flying Trousers, Aero Leather Clothing Company. Size 40 (Size Tag is keyed to Crewmember's Chest Size, actual Waist Size is a 26-28). In above-average condition, with no blowouts to the leather, as is virtually always encountered. Zippers look sound, but I have not tried to zip them up - they would need to be liberally lubricated before even attempting it. Even then, it's always risky.
