King's American and the pewter local militia have seen better days, but the Royal Artillery isn't bad. I hunted the same place a few weeks ago with a similar result, only then the King's button was decent and the Artillery not great.
Recovering such antiquity is a thrill. Love the buttons. Those three cannons with cannon balls look wonderful. Even when the buttons come out of the ground pretty rough just knowing their history is enough to give them a place of honor. Well done.
