Very old FIDELITY motor from Lancaster Pennsylvania great for display in the collection. Fan collectors might be interested since FIDELITY made fans. The thing works, I tried it. It stops in the off position and either on works, just makes it go in the opposite direction. It looks like it was a buffer on the taper side. Great go along piece. It is kind of small, the round motor being about 4 1/4" in diameter. Check out the photo's for condition.
