I've heard about the lead plate. Pretty cool stuff. Malvern may be a good lead though it is pretty built up now. I was actually looking for the (General) Trimble mine. I know where this mill was. A decendant was looking for some of his papers that have been handed down through the family. It is walking distance from the Paoli Massacre too. The General Wayne Inn in Malvern is from the 1700's and serves a great meal...
