What is it?

[root]

Dug today from a turn of the century dump. It's some sort of composite material and fairly heavy. There is a cutout that is rounded and the hole goes all the way through.
Anybody?

I'm curios too. I found one 35 years ago and someone told me what it was. But since then, I've forgotten.

Can we see a larger photo or a close up? Hard to tell at this point.
