Mystery Find

It's heavy. Metal. Thick. Not flexible. No markings.

I found it at an estate sale and when I inquired, the kids said "Dad had it hanging on the wall."

I'm clueless. Do you know or have any theories as to what its original purpose was?

And if you don't know what it was meant for, tell me. What would you do with it?

Happy Weekend!
