I found this old vise at a garage sale about 4 years ago for $5 and it has just been sitting on the floor of my garage ever since. I got it out tonight to see what it might take to make it useable again. Plenty of surface rust on it and no handle. I have no idea of it's age but I don't think it is a real valuable antique. Probable worth more than the $5 I paid though. I'm unsure if I should just wipe it off and leave the patina or do a full scrub and grinding down to the metal.
It says it's from the Abernathy Vise and Tool Company Chicago Ill. No70. Roller Nut Rapid Acting Screw Vise. Then it has the letters (TAPPD FO). I don't know what that means. Where the handle goes it has the number 70A. Also on the front face it looks like there is some kind of insert (dog maybe). It does not move so I'm unsure of it as well.
So use as is or grind it down clean?
