Well, it's been a LOOOONG day but I'm back from Madrid with a nice haul:
12" Zenith BW with leather cabinet and the CRT loose from its mounts (US market model)
12" General Electrica Espaņola BW in original avocado green cabinet, with factory-supplied vinyl logo cover
19" Philco Townhouse (pictured above, that is the actual set) with the line cord cut off but otherwise complete
12" Zenith BW as above but without leather and CRT where it should be (Spanish market model)
1966 Grundig teak console stereo with 6BQ5 amplifier, Dual record changer, and two Grundig reel-to-reel decks, complete with stereo microphone still in its factory box
These were all just appetizers, on to the main event:
I got the Predicta. CRT filament had continuity. It was sitting on a table, under a very dusty sheet in an otherwise empty flat in an old building. According to the woman who sold it to me, it belonged to an American who worked in the US embassy in the early 60s. He left it behind when he returned to the US. The flat has been empty ever since (there seemed to be an interesting story there but she wasn't forthcoming). She said the neither the flat nor the set have been touched since the early 60s. I'm inclined to believe her, considering there is not one scratch, nor blemish, nor pitted brass, nor rubbed-off knob-letter, anywhere on the set, with the exception of a 1/4" rub mark on top of the CRT housing, just in front of the brass band - you can feel it more than see it. The set was still plugged into a cute li'l bakelite stepdown transformer.
A few quick phone pics, I'll post better ones tomorrow once I move it out of the garage:
