It was resting on top of the vice screw behind the fixed jaw, so it
didn't affect the operation of the vice. The question is, what is it?

Looks important, but I don't see any wear through the gunk to indicate
that it has recently been a part of something moving. ?

Both screw threads are right handed and it says "T22 HF" on the
large end.

Any idea what it is?

Well, it's a bidirectional T22 HF (RH), obviously. Now, you just have
to find out what it's _for_.
