Jaws are 7" wide. 

I think I got this vise from my father.   He was frequenting school auctions for a while.

I've had it for 10+ years.

It needs a handle.   You can go with a length of 3/4" pipe with two caps or you can use a length of 1" hardwood dowel and cross drill the dowel and secure in place with short pins of wood.  Or just buy a ready made handle.   In either case, a handle is very simple to add. 

It was dirty so I took it apart and cleaned it and then shot a light coat of Rustoleum Machine Gray Enamel on it to prevent rust.

The rolling nut is in very good shape.  No wear is visible on the brass/bronze teeth.  

I lubed and reassembled it.   

The dog moves up and down as it should.   There must be a spring behind it since it stays up when pushed up.

Its ready to work!
