What you have there....Oh wait......You don't have it, someone else has it.... is a very nice looking, very old (as in 1920 or earlier) Prentiss vise with a swiveling rear jaw. If you measure the jaw width, I can even tell you the model. Look on the main body of the vise about 2" behind that bolt sticking out like a sore thumb and you might see some very faint lettering. The real early ones had the model numbers up high there and had that dreadful (just like mine) swivel lock button that takes a pry bar to lift. Young Jedi, the girl left with the other guy, your dog left in your stolen pickup truck, and mama just got run over by a train. This thread is now officially a contry music song....
