The vintage 7 woodworkers vise is designed to be mounted under a workbench for woodworking tasks. It is a collectible tool that would be commonly used in carpentry and woodworking projects.
Photos provided are of two different vises of the same brand and model. The model number is 10-B. I believe the B refers to bench, but not totally positive of that. Only difference is one is a bit cleaner than the other. If item quantity on listing is two and you have a preference for one over another just let me know.
