look to be a post pass plate you put on your car, ft campell ky used to do that , neat if you get it it is U.S ARMY AIR CORPS,,, not AIR FORCE so it should date late as 1948 if i rember correctly when it changed to air force
Post it in the "What is it" forum, will get a lot more attention there! What Is It? Thought about the grave marker thing, but can't figure out why there would be place for a number. Racking my brains right now to figure this out!
I really don't wanna sell it if it belongs on a grave marker but I've searched and searched very hard and nobody seems to have a real answer everyone has a good guess tho hahaha and thanks for looking!! and there are dozens of people searching with no luck !!
