Although i could not find one that looks exactly like yours, maybe the pumping handle off an old blacksmiths bellow? If you turned your first picture upside down?
A very interesting find. I don't believe it would work as a simple hanger for cooking; the balance is all wrong.
I'm guessing the feature I have circled in this pic is a hollow tube?
If so, what is the internal diameter of the tube - and what is the width of the hole through the shaft near the bent tip end? I suspect that they are connected somehow - maybe by a cord or strap running through them?
