There is no plaque on the motor and it is stamped on the outside of the motor itself. This is one of the holy grails of the american electric fans. The first pat’d date is may 17 1887 and the last date is June 25 1901. It has a knob on the back you push or pull and it has a little plaque that is marked OFF. This is a stationary fan and it has a candle stick looking base to it. The seriel number is 177—, I’ve had it almost 10 years but have never tested it and the motor spins freely. I meant to restore it myself but never had time so don’t miss out on this antique fan. I don’t want to sell it but it needs a new life and belongs in someone’s collection so i hope someone can give that.
