First off, I don't know what this is. I need a little help.
Made of: Iron/Steel (rusty)
Dimensions: ~3 x 5 inches on the base, tapering app. ¼ inch on all four sides at the top, weighs about ten pounds
The indentation in the top is about an inch deep, maybe 1½ inches across and 2½-3 inches in length. Bullet-shaped, flat on one end, rounded on the other.
Kinda looks like half of some kind of mold, or something.
Found on the grounds of a 100 (+/-) year old house.
That's all I got.
It's old, and it's heavy...gotta be worth something, right?
