Strange hinged piece...

[Fooleeze]

Hello all, I come seeking help with a strange item I found today. It's a large leaf-shaped object. It measures about 3 inches long and 2 1/2 inches wide. It has a small hole for a hinge on the flat side. It has a general shape of a leaf, not sure it's supposed to be a leaf though. I'm not positive of the material, it is a little heavier, perhaps a pewter or something? It feels harder than lead. It is non-ferrous, and doesn't seem like brass.

I'm kinda stumped, so any ideas are welcome. Thanks!

No idea, but it is very cool. Good going.

Bumping this up, does anyone have any ideas with this?
