The object is a vintage fire hydrant wrench, specifically one marked "W F E CO" and "600". These tools were designed to open and close fire hydrants, allowing firefighters to access the water supply. The "W.F.E. Co." on the wrench stands for West Fire Equipment Company, which was a maker of such tools.
- Purpose: Used for operating fire hydrants and tightening fire hoses.
- Markings: The tool is stamped with the manufacturer's name, "W F E CO," and the number "600".
- Design: It has a hook on one end and a pentagon-shaped socket on the other, designed to fit a specific type of hydrant nut. The wrench's design, which can also include a spanner function for hoses, was intended to be compact enough to fit in a firefighter's gear pocket.
