I bought this at the Expo show three or four years ago. These non-oscilators of this time are less common then the oscillators as the oscillating mechanisms had become streamlined by the late teens, this fan dates to around 1919-1920 and is the stationary version of the 27646. I paid $120 for it at the time and had no idea of fan values, but knowing what I do now, that was a fair price.

Edit: I sold this fan a month ago for $150 to finance the purchase of an Emerson 1010.
