Picked some parts over the weekend and found this fan assembly. It has Buick written on it but not sure that is right. The front plate has Motive Fan and Bearing Company, patented March 11, 1921; May 17 1921.
Sure looks like "Buick" as written in paint on the fan hub.
1925 Buick Master Six
It must be Buick. The writing on the face of the fan is more of a stencil instead of hand written. The photo sure shows the same features. Thanks Dan.
