AN-H-15 with A10 o2 mask!
A classic set up.
My buddy, the B-17 left waist gunner said that is what he wore the AN-H-15 in '44

The one I picked up was a medium and it was that one that let me know I would need a XLarge to fit my head!!!

Nice set up. Luv It!!

You do look like your doing "G" testing and your about to go out!!!
