Specific clamp?

[Modern Garage]

I found this at the ReStore a few days ago. At first it reminded me of a battery terminal puller but I realized that it's a clamp after picked it up. Its coated with a very thin bright plating of some kind and I can find no markings on it anywhere. I can understand that no one was proud enough to put their name on it as it's pretty cheaply made but I just like it. I'll likely clamp it to the edge of a shelf and hang something from the single hole in the wing nut. Yeah, the dies (or molds) we're so worn out that the wing only has one complete hole...
So anyway, I've never seen a clamp like this before. Is it simply "a clamp" or does it have a specific purpose or at least it's own descriptive name?

No clue what this is, but excellent photo!

I'm guessing a spring compressor.

What does the inside/outside of the jaws look like?

no neat sig line

Guessing by your comment on the holes it's some type of valve spring compressor maybe.

Chain tensioner for installing master links maybe...

I thought about a spring compressor too but I don't think it's strongly enough made to work on even a small engine or car door spring. The jaws are dead flat and square, a little over 3/4 inch wide. The inside was filled with sawdust so the PO at least was using it as a wood clamp.
It's currently clamped to a ceiling joist in my workroom with a lamp hanging from it.
