This Model “C” Wheat electric cap lamp was manufactured by the Koehler Manufacturing Company of Marlborough, Massachusetts around 1927. The lamp consists of a battery in a case that was worn on the miner’s belt and flexible rubber cord that travels to the electric cap lamp which was worn on the miner’s helmet. The side of the battery case bears the Department of the Interior’s Bureau of Mines “Permissible” stamp marking it as safe for use in mines. The Wheat lamp was invented by Grant Wheat and manufactured by the Koehler Manufacturing Company. This lamp belonged to Grant Wheat’s personal collection that was donated to the museum in 1962.
