Well it's a GJ vise now. I just bought it over the phone for $60 to be picked up tomorrow.
It was at a pawn shop and they didn't really want to hold it as they just got it in, so instead of it possibly being gone tomorrow I decided I would take a chance. It has 4" jaws, model 46110, and is a quick release in that you back it off a couple turns and then slide the dynamic jaw in or out to your work piece then tighten it. This is a pic of the other side.
Should be worth it just for the cool factor.
