I purchased this wrench 2 weeks ago on eBay and it just arrived at the house yesterday. It was in the possession of the USPS for those 2 weeks. It is a quick adjust buggy wrench patented by Frederick A. Wegner on February 11, 1890, patent 420,981. Maybe they delivered it by a horse and buggy to my local post office. The wrench is 11 1/2 inches long. A hammer poll is on the back of the upper stationary jaw.
