Late Monday Mystery...

I was cleaning up in an old barn today, and happened upon this device, the use I can’t even imagine. It’s about 3 1/4” long and opens symmetrically. There are small points in the “jaws” and then the adjustable arm with another point on it. Any ideas, anyone?

Update; see comment from reader "pzak" for the most likely identification. I will talk to a watchmaker contact to see how it might be used.

Some type of thread gage is what it brings to my mind

Its a diabolical set of thumb cuffs:)

I'm finding a few "figure 8 calipers" used in dental prosthetic work
that look very similar, if a little less elaborate.

Thanks, guys! It looks like we've figured it out! I cannot imagine why that would have been located in a barn.
