I'm not on here ALL the time, but what I THINK is being said here is some guns produced in the North after the beginning of hostilities may have been used by the South, and this is a projectile from one of those guns. Now, whether the projectile was produced in the North or South, I have no idea, but it does have a lead hollow sabot cast on the base.... If I am completely off base, someone please correct me before I make a complete fool of myself.
