b.w, that is a versa vise as mentioned, - gun smiths vise. that one is a parrot jaw, most you see are Bull dog jaws.
The last pic is a Parker, I think an old one.
Thanks for all the responses.
I could definitely use the first one with the "parrot jaw" and then still a ~4" machinist vise. The old "parker" would work (last pic).
The restored looking black paint vise still unsure about that one. "looks" to have the widest jaw. It's got a full body (lots of metal). but still could be anything as far as I can tell.
va.grouseman, which one do you think is the wilton in my pics?
mines still got the cover for the screw which I don't imagine survives very often, the patches of paint also to show how it was once dressed. I like it more now I know it's approx age, one of my older ones.
