9 Inch Robbins & Myers Company 2 Speed Fan, 120 Volt AC. Manufactured in Springfield, Ohio between 1900 and 1902 from what I have read. The grille around the fan blades has been painted and the brass fan blades themselves have been shined and protected by clear spray varnish. Everything else is original. I ran the fan for over 20 hours to make sure that it works ok. It is a little noisy, probably due to being dropped at one time. Runs great for being 100 years old. Look at the pictures, this is a nice looking fan.
