EL35, metal base?

[mosfetmaniac]

I recently uncovered an el35 in my collection, it's unlike every other EL35 I have which are usually coke bottle shaped and have an octal base.

The tube itself looks more like metal base EL34, or an EL60 with a built in Loctal to Octal converter.

I've never seen one of these, just curious whether anyone else has seen one?

Hi,
I had a quick squint on the National Valve Museum and spotted an EL35 sensible equivalent which is a 6L6GTY. This has a straight sided envelope and a metal octal base, but no built in adaptor.
Hope this helpful.
Cheers, Pete

I have a taken a couple of shots of the EL35 (R/H side) with some EL34's beside it for comparison, as you can see it's nothing like the normal classic shaped EL35's.

I'm also curious about the black base EL34 on the left, it's lost the manufacturer label on the glass but has a 3 digit code on the base like most Telefunkens do, however it has an XF2 B3J3 code on the side and a hole in the base tip like Mullards.
Did Mullard manufacture EL34's for TFK?

And while on the topic of identifying tubes, here's another which I cant seem to work out who the manufacturer is?
Its a CV2492 = E88CC = 6922

It doesn't look like a Philips or Mullard due to the lack of dimples on the top of the glass, possibly GEC?

Any thoughts?

I just remembered I had some EL60's in the drawer, the EL35 looks almost idential with the exception of the base.

The military code KB/AD indicates that this valve was made by Brimar in their Rochester factory.
