VTG Westinghouse AM20-6 Adjustable Industrial 2-Speed Floor Stand Fan. Has 2 speeds and runs smooth and strong. Adjusts from around 3 feet to close to 4 feet high. The blades have dust on them as I did not take this fan apart. This color scheme shows it to be from mid 1960s. Definitely could use as is. It is held on by 2 screws.
