My father made something like that while he was aboard ship. Had the Statue of Liberty tapped into a brass casing with a center punch and a steel projectile with three pipe-threaded holes in it. It was meant to be a gas light stand --that's how long ago it was. It was in three pieces, base, shell, and projectile, held together by the base and projectile being screwed toether with a long pipe in the centerline.
Wife1 and I had it in the old house in New York and had to leave it there with many other "valuable" things when we moved out to Colorado.
A couple of years later my mother sold the house and left all those goodies in there.
If anyone ever sees an artifact like that (looked like about 3"-4" caliber, from my memory) I'd sure like to know what happened to it.
Long shot, but who knows?
