This beautiful antique General Electric three speed brass electric fan has been restored in a green color and all three speeds are working and it runs smoothly. I assume the blades are brass as a magnet does not stick. The cage measures about 17″ in diameter with the fan about 20″ tall and one blade has a small nick out of it but other than that it look excellent. The brass tag states it is type AOU, form AC1, no D143580 and cat 75425.
