Found this pocket watch key and possible CW button this afternoon (just as possible the button is civilian). I have dug a NY cuff, 2 Merrill Carbines, 3 ringer, pocket watch, thimbles and at least a couple of dozen flat buttons in this site previously. It is next to a water common in a small ghost town near the TN River that started around 1812 and died out in the late 1800's. The area had heavy troop movement from both sides during the CW. Think it is the first watch key I have dug. I beat the site to death with my G2 but had been waiting to try the new T2 SE on it. They finally cut it this morning.
