This is an interesting tunic and helmet in that I got it from a WWII vet that brought it back with a bunch of Nazi stuff.
His name Was John J Stidham. He was in the First Special Service Forces from the beginning of that unit and when it was disbanded was transfered to the 505th Airborne Battalion until his honorable discharge at the end of the war. I knew him as the manager of the local electric office in Picher, Oklahoma. He was a good guy. Rough as an old boot but a nice guy.
The Helmet chinstrap leather is replaced. It was broken with a piece of the leather missing and I took the hardware and made a new leather piece.
