A POS 30# Parrott shell, no sabot, but has this iron ring inserted into the fuse hole, which makes it unique. Can't tell if the ring is threaded or if it was hammered or pressed into the hole. I've ran it twice and messed around with it some but cannot remove it. I believe in the old medical oath "First, do no harm" so I have not put a lot of force to it. The ring is wrought iron and appears to be contemporary with the projectile.
Anyway, it came from Fort Fisher. Anyone ever seen such a thing? I've heard converted to anchor, but I don't buy that. Throwing rope or cable? Make shift bolt conversion?
