I picked up this fan at Hershey last year because it looks sort of like Model T, but it has six blades. Now I see someone has a picture of one on Facebook calling it a 1908 Model T fan. Did Ford ever use a fan like this?
My guess is a Dodge in the mid to late teens.
The really early T's had a 6 blade fan that was gear driven. It was nothing like the one you show. I agree, it looks like a Dodge fan.
