I picked up this Columbian made Craftsman vise for $25 the other day from a local pawn shop. Jaws are perfect, paint is pretty darn good. It saw very little use. Its got 4" jaws with a 6" opening, which was an improvement over my Record vise. I'm guessing its early 70s, but does anyone know for sure? The 72-73 Sears catalog has similar model numbers, but they had letter suffixes which this one does not have. The 68 catalog had a 3" and 5" vise listed, but not a 4".
