It is unusual to see the original battery holder extant with these pulp JOLs. To eliminate the risk of fire due to burning a candle, this manufacturer changed their mold to enable a battery holder with bulb to be attached to the back. This seller obtained this particular pulp JOL through me some years ago. He’s a great guy and a knowledgeable collector.
