That's my memory too - i.e. the red or aluminium cans were EF50s. Why some
were red I don't think I ever knew.

Is it not so that the red EF50 was the original one, developed by Philips
at
Eindhoven for television treceivers? Just before Germany occupied The
Netherlands on May 10th, 1940, info on the production of the EF50 was
passed
to on Mullard.
The aluminium military equivalent of the EF50 was the VR136, which was
used
in for instance tuning units of the Gee set; one as RF amplifier, one as
a mixer and a VR137 triode as oscillator.
