That vise was made by Columbian. The jaws should have teeth on one side and be smooth on the other side. If the bolts can be removed, the jaws can be flipped over. A new set of jaws will probably cost as much or more than the asking price.
Otherwise, it's a good medium duty vise for general garage or bench work.
I bought the Craftman labeled version in 1989 and it still looks nearly new after almost 30yrs of hard, but careful, use.
