Does anyone have, or have links to pictures of the Aurora Automatic Machinery Company?

aka The company that produced Thor motorcycles and engines in the early 1900's. Later they produced power tools and home appliances. They were located at 340 State Street in Aurora Illinois, which according to Google Maps is now a suburban subdivision :( I found some internal pictures of the factory floor, but I am looking for exterior pictures of the building itself. Any help is appreciated! TIA
