Original 1910 12" Dayton Tab Base Desk Fan. This example still retains a really nice original finish that is 108 years old. The cast iron tab base is a very desirable feature of this fan. This fan is built so solid!!! In assessing the fan, the guard may be newer production but cannot guarantee. The fan runs excellent on 3 speeds. As you can see from a photo below, the switch has a crack in the body but it doesn't affect how it works. A very nice collectible fan!!!
