Tonight on our local PBS station a fellow had a clock on the Antiques Road Show that was very old and stated that some of the weights inside were replacements since the original lead weights were melted for bullets during the American Civil War. This got me thinking and I wonder if any history buffs on the forum might know some answers. Where were the predominant lead mines for both the North and the South, and were their known companies supplying lead shot for both sides or was this a personal project where individuals made their own shot between battles? Thanks...
