Hello, I've had this vise for a year or two now and I've only been able to find an old Milwaukee website describing these Morgan Star vises specs, but I haven't found any forums or anything else describing these vises and was wondering if anyone knew about the star vises in particular.
Hello, I recently got a very similar swivel jaw vise to yours. I found your post looking for information on the vise after I'd restored it. It's a no.51 with 4 inch jaws, to confirm what you said.
