What's the value of old face-mount woodworking vises these days? You know, the kind that were mounted to each corner of the 4' square workbench in your school wood shop, that had the sliding dog in the front, and were usually gummed up beyond recognition with several layers of paint, glue and chew spit. It seems like nobody uses them anymore, between the tail vises, face vises, Roubo-benches and every other kind of wood-holding method there is. I have a brand-new Shop Fox QR vise that I've owned for 15 years and it's never been mounted on a bench and used, and an old Brodhead-Garrett that must have been on a school shop bench for 50 years, judging from the layers of crud. I am not sure if these things are even worth using at this point, but on the other hand, it seems like a solid bench and vise with a functioning sliding dog, and a bunch of dog holes in the bench, what more do you need?
