Default Valve Identification

Is anyone able to ID this transmitting triode please? The only marking is 561 X. Very many thanks.
Regards,
Richard

I have a similar triode. And a base for it! I'm wondering whether to make an audio amplifier, or a pantry transmitter.

That would make one hell of a 'Pantry-transmitter"...
