Hi, I've had this vise for a long time and always wondered what it's intended trade was. It is a bit different than any I've seen. It has 4 1/2" wide jaws and 1" screw diameter. I also wanted to try posting pictures.

WOW I'm impressed. You guys are good. I thought I had made a pretty good effort looking for info on this vise but found very little. Now I'm wondering if I should continue using this vise. I'm not rough on them but ... My Reed 104 sees the most use. It really surprises me how often I use that vise every day.
Thanks again for the research and information. I will post the pics on " Vises of Garage Journal " as suggested by Catalyze.
