Early Electric Wheat Cap Lamp

This is an early version of Grant Wheat’s electric cap lamp. The lamp consists of a black battery box with a cord to the cap lamp. The point where the wire enters the battery and the cap lamp is protected by circular metal spring-like rings. The black battery pack has a clip so it can be worn on the miner’s belt. This lamp belonged to Grant Wheat’s personal collection that was donated to the museum in 1962.
