That's a nice Thai sword! You know, my grandfather's family from my mother are soldiers. I heard they are from a long line of soldier, even my grandfather was a soldier during WW II. His uncle was the king's soldier inside the palace. I think he has a title of Paya...I think that's equivalent of commandant, I'm not quite sure, though. Maybe when go back to Thailand, I could find out if any of them have some Thai sword antiques, which I might offer to buy, being American money is so expensive, that would be no problem.
