What is this?

[Lord Bob]

I've cleaned it up from when I got it, and I have no idea what it is or what it goes to.
Thanks for any suggestions.

I have no idea. Perhaps it came from outer space?
It looks like it might be some kind of wrench.

It's either a thingamajig or a whatchamacallit.

Looks like it could be an old wrench for Colt revolvers. The middle space would be for the cylinder ratchet. I could be wrong, too.
