Cleveland Thurman Campaign Item

Submitted by Kelly: I was trying to identify an item that belonged to my dad. I don't know where to search. I have tried websites but nothing comes up. It looks like a clasp from bib overalls strap. Think possibly brass. All it has on it is cleveland & thurman. Do you possibly know what it is? I thought of a overalls company. Sports item. City item. Nothing i can find. He had it wrapped like it might have some value but I have no clue. If you could help i would appreciate it. If you can help Kelly please click on the Comment button. Thanks!
