Interesting take on the design of the mica spacers.
I always looked at the metal fingers as the primo method of locating the electrodes in the envelope. The first (and best IMO) 807s used the fingers as did the original metal base RCA 7027. And then there were the Bendix "Red Bank" series of tubes that used metal things well evolved beyond fingers that were used to locate the ceramic discs used in place of mica. If metal fingers were good enough for 60s era nukes, who am I to argue?
