If you wasnt a Navy guy I wouldnt tell.
Shawnee has some good ones, as does Okmulgee. Theres a decent flea market on 75 just outside Okmulgee that I frequent, good buys usually.
My favorite place to buy "junk" is Marys Flea Market.
Forgot about Shawnee and Mary's is always good sometimes I also have been told about Sulfur on Sat has a great flea market as well. Keep them coming this is helping out finding some new places to go to.
