Just got this 6 - inch vise that originally came from the Tredegar Ironworks in Richmond, Virginia. The fellow I bought it from said his great grandfather had worked as a Blacksmith and a puddler in the foundry there and when the equipment was auctioned off in the 1950s, his father bought some of the blacksmith equipment including this vise and some tongs I also bought from him. I cannot find any marks on the vise yet, but haven’t cleaned it up and removed the paint to look closely either. Based on what I have read here and what i’ve Seen in the past, I am thinking it is pre-1900, maybe even around the civil war based upon the mount and hexagonal shapes on the vise legs. Screw is in great shape. Jaws are 6-inches. If you need more pics to help me figure about how old, let me know what you need. I realize this all best guess, but I appreciate any and all ideas, suggestions, and help.
