This was modeled based in a set of photos from some different fans designed by Peter Beherens (http://en.wikipedia.org/wiki/Peter_Behrens).
The model is may be a bit heavy because everything has a lot of subsurf. The materials aren't configured in blender, as it was rendered in Octane. It won't be a difficult though.
It'll be nice to apply some scratches textures making it look old.
This is amazing
