Andy, I have looked at hundreds of buttons too and not a one with a divided shield like that one. One fella did mentioin it, and said it was a scratch.He no doubt did not take a good look because it is in no way a scratch. I can almost discern a # 3 or 5 above the bar. Lol, I remind myself of a buddy of mine that can look at a slick button and see Andrew Jackson with his cannon, flags, troops, and eagles all lined up at the battle of New Orleans. It does though look much like the modern 1 st Cav.Shield.I have a hunch it could be an early Militia Button but don't know that there would be any more knowledge about them than the other early Eagle buttons, and they are all in the earlier time periods. My friend's husband bought her the Cibola right after my first mention of it before I really had studied up on what would really fit her. They are serious (and very good at it too) Archaeology hobbists, and I was not sure if it would do what they need. Now I need to help her get good with it so I won't feel I lsteerd them wrong. It will work with y'all's good advice and I will feel better about the situation.Many Thanks again, HH, Charlie
