Heavy bidding last night on quality wrenches that were offered in the online only Donnelly auction. It appears the top wrench was a Joseph Hyde patented wrench that might be the only one that has come to market so far. Looks like it sold for $3,300 + buyers premium, taxes and shipping. Several other quality wrenches brought strong money.
The Hyde patent is for a worm screw quick adjust wrench where the worm screw is mounted on an eccentric shaft.
