Anyone recognize these? Just inherited some and I think they’re supposed to be a shaky head but the design of it has me confused.

I can't believe you stumped this crowd. I don't think I've ever seen one of these type posts go unanswered. Maybe it's custom, a one-time thing.

 

It looks like it might be to pinch the plastic and make the bait-keeper work better. I don't think it's a shaky head - line tie is too far forward.

 

 

I can't remember the name of them, but I believe these were designed to go with a soft plastic craw and fish as a shakyhead. The craw was threaded onto the hook and then the tail was pushed onto the barbs to hold it into place. I could be remembering that all wrong, but I'm pretty sure that's what it was.

That’s a new one for me. The “wings” look like they were designed to be a bait keeper of some sort.

This is a strange one indeed, I have a new theory that it may be a tube insert jig head as the guy I got these from was really into tubes, but if so I don’t know why you’d want to elongate the head vertically. Edit: well scratch that, it would make no sense to paint them if they were designed as an insert.
