a 3/4" brass faced button with the words Ox over the word Horn on the face, it has a iron back and loop and is constructed like a two piece civil war button. It is too light a button to have came from something like a pair of overalls it would have been made for a button hole. It was found in the middle of union cavalry artifacts on an Arkansas campsite. I don't think it's civil war, but just checking, has anyone ever seen a button like this. I've been unable to find anything on this button.
