Machine age vintage Air Castle electric fan, heavy industrial steel fan

Vintage industrial steel fan made by Air Castle - Chicago, with an unusually interesting steel base, deco style open circle shape.

It's 14" in diameter across the metal cage, not an oscillating fan, but very powerful and quiet. It's a single speed, with original switch and wiring in very good working condition.

There's soil, grease and light rust spotting to the fan blades, cage, base and motor housing - we haven't touched it.
