Antique General Electric Fan from early 1900s.
Plate shows Number 509803. Most Recent Patent year date: 1901.
Fan Works at all 3 speeds :
Level 1 is apparently the highest level; levels 2 and 3 are quite a bit slower, so I'm not sure if the adjustment is working properly, as designed.
Please note: I'm quite sure that this is NOT an oscillating type however.
