This is a Wilton heavy duty machinists vice. It is marked #101157 and #101158 and those are for a Model 400 Machinist vice. 4” inch jaws. The key way is stamped 5 - 85. So it was made in May 1985. It is in really great shape. Insides, threaded shaft, handle and jaws were cleaned and coated in Remington gun oil. When you get you will grease it with your grease. It has a little of the original paint. Outside is lightly rusted. No heavy rust. A wire wheel will clean it. Weighs all most 50 pounds. No swivel base. No cracks, chips or welds.
