What is this metal object?

NOT the key.......wiseguys.

Seems to be cast steel, weighty. Just found on the warehouse floor here in central Florida. All searches come up with items that are close, but not close enough. No threading inside. No packaging found.

It's a tub drain removal tool the spiral is left handed to loosen the threaded drain in a bathtub. Square in the top is to use a ratchet to turn.
