VINTAGE REVERE PORCELAIN PYREX GAS INDUSTRIAL LIGHT LAMP FIXTURE PARTS , nice early fixture, the only porcelain chip damage i see is on the very top, standard 1/2″ pipe thread mount, needs cleaned, 16″ tall and 14 wide, the inside looks to me like it has the standard white porcelain but it has been factory lined with a aluminum reflector. No breaks or cracks.
