Circa 1910 Jost (Germany) Patent Radio Fan. This Fan Came to Us From a Collection Liquidation and is a First for Us. To Our Knowledge, This Example Appears Complete. The Burner has a Transition Chimney That Will Not Fit Under the Fan. This Transition Chimney Appears it has had Mica Winds Originally. The Transition Chimney is Also Fragile. The Wooden Base Has a Split That Would be an Easy Repair. The Piston Moves Freely so We Imagine the Fan Will Run With a Well Positioned Burner.
