The reply I tried to send before the above one is still held up, I guess, probably by a stock photo of black Brimar 6V6Gs with GEC decals.
But here's what I wrote:
" Nice photos, Paul. Yes, the mini KT66, I have some just like that. I agree that the details on top are a key identifier- are you satisfied they're a match to Oatie's?
Since we've come this far, though, here's the rub about identifying the actual maker: the GEC decal is a commercial label that is not part of the gov't/mil standards marking. It could be (and was) applied by M-OV to valves sourced from other factories, valves that may have been marked re: other standards, etc. That is, the GEC decal is not specific to a factory of origin in the way that, say, a "KB/Z" coding is specific to Hammersmith/M-OV.
So, for example, I have numerous 6V6Gs that have that have virtually identical GEC decals, also R.A.F. related "10E" codes, but were clearly made by Brimar, and have Brimar S.T.C.F. markings on the base.
Here's a stock photo of a couple, although unfortunately without any other markings showing, maybe I can get some more photos up later:
****
So, one question is, did GEC/M-OV really make the GECs in the last photos (***Pauls)? I believe I've seen versions of those with reliable "T' factory codes, but now it's on me to come up with proof! "
Another question relevant to this thread is: which of all these fine valves, if any, actually match up on physical characteristics?
Regarding the seemingly compromised Tungsram circle logos, those tubes were advertised as Mullards, make of that what you will.
