Nice vintage industrial factory exterior hanging ceiling light fixture with jelly jar style glass shade. The fixture is metal. The glass shade is marked lights incorporated code 52145 made in USA. PYREX The glass shade has no cracks but has a few small chips on the raised rib sections.  The shade is held on to the fixture with a clip clamp.  The wire, porcelain socket and top mounting plate are new, and the light does work as tested.   Overall good, salvaged condition. Please look over the pictures carefully and ask any questions if needed. Thanks for looking.
