I got this in an auction lot a couple of weeks ago. No help from the other box contents - it was a very mixed lot of rust related to woodworking/metalworking/trash.
The only mark is an R in a diamond which, surprisingly, Alloy Artifacts (a website I like with lots of old-maker info) has no information on, so I don't even know who made it.
It reminds me of something you'd use like a pulley puller but there's just a clamp part, nothing to pull with. Tightening the screw moves those two jaws closer, loosening moves them farther. And that's about all I can tell that it does.
