Manfacturer: North American Lamp Company
This is just a regular 260 watt carbon filament lamp like the Hickory A-23 shown here and most G-25 ones, but this one has the larger and unusual P-30 envelope. The reason for this envelope is unknown, but maybe for applications where a softer heating effect is desired.
