I can just now see the French guys from "Monty Python and the Holy Grail" hanging out the windows. I did a google earth on that one building in France, and if it is the same, the pin is somewhat fictionalized. It is a pin, no doubt about it, about the size of an average kepi letter. I don't think it was made in the US. I went through Tice's button book last night and there are no matches anywhere for it. Nothing even close. There were no world's fairs back then, the house burned in 1864. Not feminine at all, so it leaves hat attachment as the likely suspect. Apparently its not "regulation" Confederate, but just like the masonic emblems, or some of the "Texas" stars that are found.
