I was in the right place at right time and wound up with a nice stash of vises being wheeled to a dumpster.. These are stamped “Jorgensen” 7x04, Adjustable Clamp Co Chicago. It appears Jorgensen closed a few years back, sold to Arrow, and now manufactures some similar stuff overseas. It also appears the new company is producing a vice very similar to this model, but not the same.
I’m curious to learn more about these things, incurring their age and looking into sourcing a few missing parts.
Other than the Chinese made look-a-like on Amazon, I can’t find much on a Google search.
Any chance someone knows anything interesting about these things?
