Is that a B-10 jacket?
When I was flying the B-24 I got to fly a wartime B-24 pilot and his family. He came to the airplane wearing the B-10 jacket that he was wearing when he bailed out of his B-24 over Europe and it had the tear in the back where it snagged going out the hatch. He also had the wooden utensils he carved to eat with while a POW.
