I've looked and looked online and I can't find one like it. It sure does look to be an old button. Is there any thing like writing on the reverse? I would think some TN member would have a clue to this button. I know there's books on old military buttons, but I don't have any. I also can't figure out what the eagle is perched on. It doesn't look like an anchor like some of the others I've looked at. A little better focused picture may help in viewing an enlargement of it.
