Greetings JT,

        Are you aware that by.pulling the pin it will allow the rear jaw to pivot.  A real handy feature. Yep looks like a Prentiss. 

      Forge on and make beautiful things

Look on the forward most plane of the vise under the screw and handle.  It should read "P V CO" and this would make it a Prentiss Vice Company swiveling rear jaw machinist's vise.   Otherwise known as a self-adjusting rear jaw vise.   

In my research, I've only seen the unique profile of the vise jaws ("U" shaped, arranged horizontally) on a Prentiss vise.  There are no visible markings on my vise other that unreserved the screw handle.
