Thanks for the insight. The threads and screw box are in very good condition. Not a lot of wear and no cracks. I see it has 2 small dots (indintations) on both sides of the arms where the jaws are attached. That is about it for markings. I just sold a very nice 130 lb Fisher Norris Anvil with Eagle logo to a young lad starting out and he asked about the vise. Thus the inquiry.
