The vise below is foot operated, built similar to leg vises. The second
slide is a video. When watching I thought the front jaw insert was
loose but now I think it is deliberate to allow the jaw to stay aligned
with its mate. One could probably do something similar for the leg
vises...

My browser doesn't render instagram but from your text: Does the vise
also have a ca. 4"x4" shelf-like projection? Could be a farrier's
caulking vise. They have that self-aligning jaw and treadle closure.
I had one 50 years ago but swapped it off for some other stuff.

The shelf would have held a "caulking block", a steel brick with
acute-angle grooves, used to support a freshly caulked shoe, caulk
down, when hammering on the hoof side.

Thats what it is.

I've also seen a foot operated vise in an optical repair shop but it
was an elegant precision tool, far from clunky old iron.
