Hello friends. As Treasurer of Neighborworks Housing Solutions, I'm donating one of my fans to the silent auction at our annual Gala. This BMY has been re-japanned by Rick Powell and polished and lacquered by me. I would like to put some information on a tag in front of the fan at the silent auction table including the date of manufacture and market value. I was thinking maybe somewhere in the 1909 to 1912 time range for this big motor yoke but I want to be accurate as possible. Perhaps someone could look up the serial number and provide that date? Also, I need to establish a value as the non-profit will give me a letter for tax purposes as to the value of the donation or should that be whatever it sells for? Your opinions please?
