1880s Antique 10" Wooden Handled Girard Pennsylvania USA Railroad Monkey Wrench

Beautiful fully functional & sturdy antique. Perfect working shape, and lovely patina. “AO” stamped into metal. It's marked "GIRARD WRENCH MFG. CO. GIRARD PA. USA.” Sold as pictured. The factory in Girard PA. that made these wrenches was reported destroyed by fire in or around 1902. To my knowledge the factory was not rebuilt.
