Has anyone out there ever seen a Champion or ITT circline lamp? I've never seen one and don't know if they've ever made them.

 That one would be interesting to know, but I do have a champion F40 U bend that is mexican made.

The one you have is probably from the 90's when Philips briefly brought back the Champion brand name and these lamps were sold primarily in Sears stores. U bends did not exist when the real Champion Lampworks existed up until 1966 when they were sold to ITT.

wow I did not know fake champion lamp exist like the fake westy. i guess find something fishy here;
as fake westy abco lamp and my F20 champion lamp. I found at restore that silverliner looked at
was made at old westy location by philips. 

There were loads of Champion branded starters in Israel in the late 80's and through the 90's. The older ones used the thin glowbottle typical to Korea made starters with the mystery purple fill. The newer ones used the random shaped bubble filled with neon, like some ultra cheap starters from China. I have a few, can give some shots

There were also Champion branded voltage tester screwdrivers (neon) in the early 2000's, i dont know if they are the same company

Never seen anything else from Champion
