My partner and I are searching for a Confederate "Boot Camp" and have pinpointed the general location although we have not yet found the camp site. Our first recovery was a harmonica reed. This past Friday we recovered two items. One appears to be a shot round ball . The other item is a small brass rivet in wood. Does any one have any idea what it could be. It was about 10" deep and the three or feet from the recovered round shot. Thanks TomB
