Re: Hudson handset
My apologies, I can only find the 'half' and I vaguely recall passing the complete set on to a PMR collector some years ago, apparently with my sketches.
Looking again, these were really rather wonderful units, with lots of relays and RF test points. Looking carefully at your photos we can see there is no PTT switch on the handset as these were fully talk-through, can't think of the proper term. This required some serious front-end filtering, even for mid-band. The 455kHz IF filtering was a big 'block' filter except these you could open up, probably even retune.
My memories of buying these are similarly vague but I remember how keen the guy was for me to take 'the lot' or at least several more; at the time everyone was buying Cambridges for 4m
