I was in my dad's basement workshop area and noticed this vise. It was covered in sawdust so I cleaned it off a bit and noticed it said "US NAVY" on it. It used to belong to my 95 year old grandfather who was in the Navy. In fact, the whole workbench belonged to him. He was a machinist. Anyhow, the vise was made in Cleveland by Colombian Vise and MFG. Co. (model 604). Any thoughts on this? Anyone have a guess on how old it is and what its value may be?
