You have a good eye. Your wrench is interesting, and signifigant :)
Walton started as the T.B. Walton Company, and was renamed The Walton Wrench Manufacturing company. The intention was to produce several sizes of a wrench based on patent 117679 (Aug 1 1871, G.B. Phillips) and half the money came from Girard.
Yes, *that* Girard....
The venture failed, and was sold at Bankrupcy in 1875, and the assets became The Girard Wrench Manufacturing Co....
