my next project age model and make unknown ? any ideas etc help ? im starting to pull the ge catalogs out this is going to be a tough one to nail down .
Looks like a GE Form 6 pendant Novalux with "stippled glass globe" to me. Those came out before rupture discs and had isolation transformers up in the luminaire body. Check out the old form sheets in the Antique Lanterns / Fixtures forum and you'll see your light. Great score! I'd love to have one some day.
If you look closely at the light it appears that the reflector has been modified. The reflector above the refractor is a different color from the body and it actually looks like a modified NEMA reflector, so I'm theorizing that an L-M teardrop might have been installed to replace the original that may have been broken. Regardless, it's a very cool score.
When you break it down to restore, please take and post photos. Hopefully it still has the original isolation transformer inside, although it could have been retrofitted with a standard mogul socket. Also when these were hung each light had an insulator cross right above the cap. The conductors between the lamp and the insulators were coiled like curly fries between the stand-offs and the insulators. The insulator cross was fixed solidly to the span wire hanger and the lamp could actually swing, so the coils allowed the luminaire to move but kept the conductors from striking metal on windy days.
