Valve line-up of British Homebrew Rig

A number of electro-archeologists out there have asked about the valves found in the old British homebrew rig I presented yesterday. Here you go:

Mic amp: ECC83

What I think is the modulator: EL84

Suspected oscillator: M8162 also marked as 12AT7 WA UJ

What looks like the driver: EL85

Final: QQVC3.10

I'll try to determine the resonant frequency of the tuned circuits.
