Rich, this is actually a bench version of a post vise and intended for metal working. Although a blacksmith might have had one of these as a secondary or small part vise, they always strike me as belonging in a farm shop. Lots of farms had a generally small inexpensive forge, I have a Buffalo version with a sheet metal pan. The bench versions of these vises show up much less than the regular post vises, but I am uncertain as to why.
