With the black part, even though it's light, and the texture of the white, I'm wondering about a Vacor Wicked Owl here.
If I'm on the right track there that would mean the pontil-looking part was some other kind of damage.
That would also make it modern. The Wicked Owl style is still for sale at Land of Marbles.
