Finds from an old army base. Either a mess hall area, or a camp dump, I'm not sure. Mostly wooded now. 2 nice 44 wheats and a 42 nickel.
The prop and wing button looks familiar, but I can't place the insignia.
Definitely an Arm Air Corps collar disc, but for an enlisted man rather than an officer. Stoney's link shows both, the officer's version being on the bottom of the first picture. Looks like a great place to detect!
