✅ SOLVED Thingamajig (missing jig?)

My friends own an antique store and they brought out this thing when I told them about this forum. I told them I'd post it and give you guys a shot at the ID. Thanks for looking!

Can you look up the patent number officially?
It could have been mounted as a sign on virtually anything.

Crazy! I knew you guys would come through. I can totally see its teeth shaped now! He's going to flip out when I tell him. Been over 5 years he's been asking folks about it.
