Picked up a heavier post vise, 5-1/4 or 5-1/2 inch jaws, estimating 80 lbs. Someone welded/brazed the mount u-bracket to the leg and a metal plate. I cannot put in a proper spring like this, thought about using a coil spring for now or adding a u-bolt but would like to get it back to a standard mount and spring by removing the welds and finding or worst case forging a mount plate. Can anyone tell me by the pics what type of mount this may have originally had? A pic of what you think it had would help as a guide if I need to forge something. It appears to be pretty old, square bolts, looks English made but have not cleaned it up to see markings, there are numbers stamped on the jaws in the style of my PW anvils font. The rest of the vise is in really nice condition, screw and box are excellent. I know it is hard from just pics, but if you could help narrow down a maker it would help in my research for a proper plate. If anyone has a lead on a spare plate and keepers from a parts vise please let me know, I'd love to keep it close to original as possible. Here are some quick before pics for now:
