GE tubes will survive after all others perish. They are the cockroach of the tube world. :smiley:

I've never seen a T-plate GE, the inner structure of the tube looks like a Sylvania W or WGT, so very likely a Sylvania rebrand.

Agreed about it not looking like a GE structure, however, the flashing doesn't come down far enough to be a Sylvie W as those are typically covered at 1/2 of the tube. I cannot really tell w/ certainty on this pic, but this looks like it may be a standard bottle. WGTs were short bottles, IIRC. THe umbrella top mica and center support rod are so characteristic of a W, however. :confused:

Below are the Rogers tubes a Spanish vender is selling. It's about the same length as Sylvania W or WGT, only anomaly is the getter flashing not going down as much as W or WGT.

So I think it's very likely a Sylvania rebrand, or at least Rogers imported the cage from Sylvania and put on their own glass and base in Canada.

W's also have an OVAL bottom mica -- not round.

Agreed!! There is definitely a Sylvania lineage here w/ the Rogers implementation closely resembling the WGT. (My guess is WGTA)
