This wood handled monkey wrench is from the late 19th or early 20th century. It has a mark on the arm next to the adjustment screw. The mark is largely worn away but enough remains to identify this wrench as being made by Peck, Stow, & Wilcox Co. The wrench still works it is not froze up. There are no cracks in the wood handle but this wrench does have the dinngs, scratches, and dirt of a tool that is 120 years old.
