That's incredible that you can tell the place of origin Frank. The vise turned up in Canada, so you are right on the mark.

I recently restored a 50lb 4.5" Peter Wright vise. I was fortunate to pick it up along with a Vaughan anvil, my first two smithing tools.

    
 
I used a drill type wire brush to strip off a layer of silver paint, then gave it a light coat of boiled linseed oil. The next challenge will be finding a solid place to mount it.
 
Another site mentions that post vises were typically forged from wrought iron or mild steel. In this case I can see that the wedge for the bracket is wrought iron, so that may be the same for the rest of the vise.
