Hi Andrew,
Eddie was conservative so his rig will probably give the same output today as when new.
The Polish resistance located in the UK built spy radios with 829B output tubes. They needed 10 dB more power to work from Poland cf France. Would have been a heavier suitcase!
I think the Rx was more sophisticated too.
Now if I could find and afford one of those…

ok, you got me now.
My project for this year. I have a Geloso VFO G-4/104, TX will be 2 - 4 W. RX and PSU to be built…
vollroehrisiert - which means quite the opposite of “fully transistorized” in German. As I grew up a generation later, I always found this slogan written on some radios of the late 60s and 70s very disturbing.
My strike back: fully tubysized

For someone wanting to build a small, rugged radio, I have some Nuvistors 6CW4 available. Nuvistors are 10x20mm.
I was in the attic of the old building of the former Radio Research Centre that studied propagation, and found a box of modules using Nuvistors. This one uses 6CW4 triodes.
The building is being demolished, and these will be dumped.
If anyone wants to use these, contact me.
This module is an adder, from the “Large Interferometer”, which recorded the azimuth and elevation of incoming HF signals. It had two vertical dipoles on an ~10m horizontal arm that rotated continuously - for many years.
This reminds me of my first and so far last use of a homebrew 3-tube TRX on a Summit.
