Here is a 80 plus year old vise ready to go to work for you.
It is listed on page 11 in this 1940 catalog http://vintagemachinery.org/pubs/11508/22107.pdf
When the handle of this vise is turned to the left against a stop, the front jaw can be slid to full opening;
a partial turn of the handle tightens the vise against the work.
Works as it should and ready for another life time of projects.
