I picked this vise off Facebook today. It was about 45 miles from home. It's a Cole Tool Mfg. from Chicago Hts , Ill. Model 11. I've seen these on CL before and I've wanted one for a while now. It mounts with one hole on the rear and swivels from side to side. It's pretty darn heavy too. I don't think the handle is original either. When warm weather ever comes back I think I'm going to paint this .
