Thanks again, that would be great! Maybe the indicator was tacked on for this chassis? I see on the scan of the model with the 6E5 it’s just hung of the AGC
So it’s trivial to add it. Your help is much appreciated.

Will do some time today.
It is possible that the indicator valve was added after chassis manufacture. The mounting is a bit unusual.

That was my thought as well

It would seem that many of these sets were actually made by National Radio Corporation P/L.

I note the 48 circuit is in AORSM's

Depending on the wire condition? Those frayed fly leads may be able to be salvaged using shrink tube. Many originally had rubber sleeving which acted not only as a strain reliver, but stopped shorting to the tube shield.

Circuit board lacquer also stops fraying.

As this is basically a badge engineered model for a specific customer, there is the thought it could have been manufactured as many were, to be a bit more up market and national used an "eye tube" common to their other models, with appropriate changes, "as necessary" to the AGC / AVC & general circuit to accommodate the eye tube.

At the extreme I have worked on a factory special, BC/SW its bits appearing but not used (used in the production model) in the parts list. In it they removed the back bias in favour of self bias, Added a bigger power transformer and used a three stage switched, delayed AGC.

Instead of the add on optional extra, plug in PP audio PA, they self biased the existing OP tube & used it for a Push pull driver for a 6A6 double triode for the amp and that was on the chassis. One of few sets that at no signal, full volume had no discernable hum.
