Identifican request - 3 Valve mains superhet

[pwdrive]

I haven't looked at it for two days on account of going out, and my 6 Volt LT batery needing recharging.       I know that the cans would come open easily enough if removed from the chassis, but they can only be removed by brute force, and having been removed, I doubt if I could get them back!     When it gets light, I will take a photograph to show you why!    I could check them by disconnecting them underneath, and a connecting each half in turn to a home-made transitron oscillator to see exactly what frequency each  LC circuit oscillates at!      Plenty other things to look at before I have to do that though - the dreadful sate of the wiring for a start.

Doing that oscillator test might not give you the frequency that they actually resonate at when they are connected in the receiver.
