Thank you Steve, thank you Russ.

How does this square with previous posts about no speed coil? Several threads have pointed out the motor windings acting as a speed control.

Are there known instances beyond this photo of an actual choke in this fan?

The top fan is 60 cycle AC, no coil. The bottom fan is DC, or at least lists no cycles listed, has the coil- 3 speed resistance wire DC....

I was under the impression vents on the cover were ac, and no vents dc.

I recognize your observation of cycles, but believe both are ac?? Maybe??

Not sure on covers. I've heard that too although I didn't notice that detail on my response. Mine has solid covers, marked 110 with no cycles, so assume DC. It also carries a Pullman tag on the base. Switch is of course gone because because a lot are, so can't verify coil. So we're back to not knowing how to square this up.....
