Have you checked the back of the pictures to see if your uncle labeled them with names?If so, you could post the names and see who responds.
Under the Freedom of Information Act (FOIA), you can request a copy of his DD214.This will tell you where he was stationed and what Unit(s) he was affiliated with along with a lot of additional information.You will probably have to provide a copy (certified or notarized) of his death certificate and provide other information.It may be worth it!!!
I know if my father was in these pictures, I'd gladly buy the albumn from you!!!!!
Good Luck with your seach on finding a home for this.
