Early 1900's Kenco Battery Fan. Of Simplistic Design, This Was An Affordable Fan For DC (Battery) Current. We Have Attached A Copy Of The Original Ad Where Kenco Bost It Would Only Cost $0.01 Per Day To Run. They Also Say It Is The Most Efficient Motor Of Its Kind On The Market At That Time. The Base And Motor Feature A Really Nice Original Finish. The Motor Has Been Fitted With A Later Production 6 Wing Pizza Cut Blade. The Base Still Retains It's Original Off And On Switch. A Very Neat Early Battery Fan!
