I can't quite see how it would mount, though.  Any
    idea?

Again, mine is a lot larger than this one on Ebay, and part of the 
"bench-side" jaw casting has three holes for mounting to the top of the workbench.  The 
one pictured looks like this part was cutoff and would require forging a yoke 
to go around the jaw base, and mount to the top of the bench like a 
conventional leg vise.  The advantages of a double-screw are the leg for strength when 
pounding on it, and that the jaws are always parallel to one another on both 
axis (like a machinist vise) unlike a leg vise where the jaws alignment is 
subject to the size of the item being held in the jaws.  Also, because of this, the 
double screw vise doesn't leave a deep mark where the one part of the jaw 
hits the item being held, because the contact area is much larger and not 
"cocked" like a leg vise jaw.
