This clamping device was on CL with the saw vise I just posted. It has a cam locking system similar to many saw vises, but the jaws are thin and long. There are 2 feet at either ends of the jaws. The jaws also piviot in 1 direction as shown in 1 of the photos but stop at 90 degrees. The inner face of one jaw is lined with a softer material like felt or leather. There is only a single screw hole at the bottom which I imagine would secure it to a work table of some sort. The words on the jaw look to be possibly "GUNN & HANNAK P G W, PA and PAT"D JULY 16,95 & NOV 24,96". I found nothing on Google search. I only gave $15 for it with the real saw vise (total $30) so no big loss.
Any ideas on actual function of this device from the extensive braintrust here? Thanks for any input.
