This vise was made by Prentiss around 1917. It's a fixed base wood worker's vise and it should weigh about 66 pounds. I can tell you that it's extremely well made and a desirable vise if there are no repairs, cracks, welds and/or missing parts.
All of that said, value will be drastically different based on your physical location. I can buy this vise pretty easily and cheaply in the mid Atlantic region. I will say that no matter where you live, you're not going to retire off flipping this tool. You'll be lucky to get 5 or 6 items at the grocery store.
Welcome.
