A few years back, I did an extensive restoration on a 80mm FPU vise. Regarding the single bolt at the back of the moving body; I've only seen these vises with two slotted set screws. These screws are there to hold the floating spindle nut in place. If they're too tight, the moving jaw will lock up.
I also examined a 100mm FPU (manufactured in Mar. '75) that I purchased several months ago. It also has the two slotted set screws to hold the spindle nut.
If the single screw at the back of the moving jaw is a factory deviation, that's an interesting find.
Here's the thread I created that goes over my FPU restoration. I hope it gives you some more information and is a fun read.
