This vise is really lightly used - it needs a cleaning as I haven't touched it since it came to me. VERY UNUSUALLY, it will hold work at an angle of up to approximately 45 degrees to the base (which has a number of differently placed mounting holes). Jaws are 3" and it opens to 3". No model numbers on this tool, but it is VERY well constructed. Thanks for looking - if you have a few minutes, I have a number of other nice tools, both collectible and user, listed among the items in my Ebay store. (G76 - 5/21)
