Hi All,
At a flea market last weekend I bought an Advance Safety Car Wrench made by the Advance Car Mover Company of Appleton WI. This "wrench" has a 5 foot handle and socket like a car mover but it has jaws that close automatically when placed on a nut and downward pressure is applied to the handle. I'm guessing it was to tighten truss rods. Does anyone else have, or have seen one of these? Does anyone have any written or oral histories mentioning their use?
Thanks
Mike Nix
