I sort of wonder were the straight bottles after the coke bottle shape? Those I would assume were the predecessors to the STR440 tubes.

I don't know which came first. But I do know the straight bottle in the picture is prior to the coke bottle in the previous post. The straight bottle does not have the label with tube color/spec seen on the coke bottle, only a color dot. But I did have straight bottle 420s that had the later label. Wish I still had those tubes.
I think it was yesterday, was looking for the information on what the Mark IV power tube choices were and noticed a different STR# STR454. Any clue what those were? Never mind, I found them, they were the SED =C=6L6GC tubes.
