Hello, I have a Knapp Monarch Duo Aire Heate/Fan, Cat. #16-504 that I would like to know about. My dad bought it many many years ago. It is in really good condition and both the heater and fan work great. I have several pictures but I can only upload one on this request. Can you tell me if this heater/fan has any significance or value? Thank you, Robin Kelly
