Nice post,
ORAC, which reminds me ...
As a child/young teen, my parents 'upgraded' to a Roberts portable and I was given the home's enormous wireless for my bedroom. Sadly not one of the ones illustrated on that website, so no positive ID. But it was getting on for 2 ft wide, in a brown [wood?] cabinet full of glowing valves and with a large semi-circular tuning dial on the front. Ah, the days of 'Hilversum', 'Luxembourg', 'Home Service', 'Light Programme' etc. etc.
The was a socket in the back panel, to which was connected a pair of [WW2?] headphones with chamois earpieces. Young MPN11 would settle into bed, plug in the headset [which then stifled the loudspeaker] and get immersed in the thrills of "Lost ... In ... Space"
