I have one like that made by Bridgeport.
Like many other old vises, the handle is missing. But an old 1/4 Allen drive works fine.
I've not taken it apart yet or cleaned it up. Project 42z6b.
But I can only imagine the gear train it must have inside it to drive the double lead screws.

I must find such an animal
I got it with my Franken mill drill. Also got that Gerardi of mine with it. I'll never bitch about it being a raw deal. The mill had a billion problems, but the kit I got with it was worth 10x what I paid for the mill.
It was my first I SUCK moment.
Only markings are a logo OTC and 897-A
Had it for 35+ years, no idea of origins.

That's funny
Here’s the part# and close-up of the logo.
It looks like a quality / well made tool.
Too funny.
Close enough if you ask me. Your Outside Thread Cleanup tool looks like theirs too.

Hmm, I wonder how my SMW Hobby Mod-Vise would work with one of my angle plates . . .
Thanks, Phineas: another item for the "After My Shoulder is Fixed" list!
And a few more unique items (some of you have already seen some of the items on display at one of the Calgary meet-ups):
1) A 3J chuck without a scroll - but the jaws still move in unison. This system uses a ring gear & pinions driving precision square threads to move the jaws.
2) Allmatic precision force multiplication / force limiting vice. Here is the link to the manufacturer:

A cross-section of the mechanism.
3) 2 foot inside / outside calipers.
4) Super high precision height setting standard (it is not 100% functional - something is wrong with the laser inside; maybe someday I’ll send it in to Mitutoyo to get repaired).
5) Some old school mechanical rpm measuring devices; they both still work perfectly.
6) A precision swivel / tilting table Made in Japan. It works well, but takes up a lot of head space on the mill table.
7) Precision angle measuring device; it reads to the arc minute and is very easy to read with the built-in loupe.
8) Etalon depth measuring calliper.

I wanted to make a small home security device that would produce the sound of a shell being racked into the chamber of a 12 ga.
Sometimes the obvious is not obvious. Well not at first.
I have a pair of TE-CO toe clamps. (Thanks to @Stuart Samuel for putting me in contact with the seller during our Forum spring meet-up)
I tried them on the mill to hold a a large flat piece of steel. They worked great but that exercise made we wish i had another pair so i could clamp from 2 directions or locations.
A light went on this morning when i saw this picture (from Darren’s post above).
Oh so obvious - just clamp down a backstop and then use one of these to clamp towards it (just like a 2 piece vise).
Wow - Just overcame another brain fart!

The OTC thread chaser I seen many years ago in my father's tool box. Well over 60 years now. It worked well, sometimes had to take a file to the jaw to remove some previous threads deeply wore into it. There were a very good assortment of thread chasers with it.
. I imagine that you could likely get other chaser sets for it as well. Never had even heard of metric or others at that time.
That tool, in hand with 3 thread files saved the day many times!
