Hi, I am hoping to get some more information about this huge vise that I bought at auction a few years ago. I couldn't find any markings except for the #10 marked in two places. As you can see, it takes up half of my truck bed! I had to load it with a forklift. The length from the bottom of the post to the top of the jaw is 37". The width of the jaws are 8". The handle alone is 24" long.
