Kemco Fan Type Generator

Good evening everyone... first post here from Upstate New York, near Utica.

I have a part that was in my grandfather's garage, then moved to my father's, and now resides in my garage! It's a "Kemco Fan Type Generator" which my father tells me was from a Pierce-Arrow.

I've done some research and found that the Kemco generators were made to fit in a number, or even most, vehicles.

However, I haven't found any information about this specific generator.

I'd like to know if they are universal, or if this is something made to fit a certain Pierce-Arrow?

Here is a link to a photo gallery of my Kemco:

I appreciate any insight that anyone can give!

Thanks!
