Unknown Table Vise
I've been wanting one of these for a while and what do you know I end up finding one on a disheveled tool cart at work today!
It's a perfect fit to be used with the X axis of a Bridgeport table - jaws and overall width is 9", and there's keys in the bottom which suggest this is the position the vise is intended for. Guess I could pop the keys out and mount it the other way if I wanted. Something weird is the keys are only 14mm instead of 5/8" in the table, guess I could make step keys.
Anyone know of a maker?

P.S. - what is the rack on the bottom for? I thought maybe moving in increments along another rack which sat in the t-slot? -

The rack on the bottom is intended to engage with a rack that sits inside the T-slot. If you tighten these table vises too much, you can spring the mill table (temporarily) which makes for tight X-axis motion at best, and potentially a bunch of other problems. The rack (which is optional) is intended to take the tightening strain rather than the mill table. Once the part is clamped between the vise jaws, the 2nd jaw is secured to the mill table.

I have one still new in the box that I bought from Enco about 30 years ago. Looked handy, but have not yet actually needed it. I think the box is marked from the maker "Free Vise," meaning the jaws are free to be bolted anywhere on the mill table. No rack on mine, as far as I recall. My mill has 7/16" slots, kind of close to 11 mm.

Nomenclature is "2 piece Milling Vise", at least on ebay and Grizzly.com
Two piece mill vises - what is the ultimate ?
You might rename this thread (or start another) as "Identify this 2 piece miling vise". -
