I'm glad to finally achieve to render my Fan into Cycles. Until today, Cycles was very unstable and crashed every time I've tried to load this.
Now it's rendering beautifully!
I insist it would be nice to apply some scratches textures making it look old.
This was modeled based in a set of photos from some different fans designed by Peter Beherens (http://en.wikipedia.org/wiki/Peter_Behrens).
Sorry, I only saw your comment now. I'm glad to see that this will be useful for you and curious about your film! I'll be following your production updates.
Amazing model - This will work well in my opening scenes for my short film. Going to work on the textures a tiny bit and animate it. I will email you when it all gets rendered. Thank you very much for this share and for making it easy to credit you since you posted your info within the blend.
