OK, time to resurrect this thread. I put the radio on the bench today, for a first look, and pulled the chassis carefully from the cabinet. It is very rusty on top.
Points of note include
1) There is no back, and it is uncertain if there ever was one. I wonder if it could have had a set-back loop antenna
2) There are two unterminated wires protruding from the chassis, connecting in to the band-switch general area. Presumably antenna/earth connections of some kind - there are no other terminals provided for this on the chassis.
3) Someone has disconnected the old electrolytics and placed replacements under the chassis. This work was quite neatly done, so I will have to decide whether to restuff the old stud-mount caps, or replace the under chassis parts.
4) Lots of paper caps, and a few in tricky places beneath the bandswitch and the preselector switching assembly.
Next up will be a power and o/p transformer health check, and a think about what is needed in general. Also a sketch of the top and underside of the chassis. Still a big question is if/how to deal with the rust. Also to determine where the loose wires connect and their purpose.
The valves look OK, as they still have the last shop test tag on them from the mid forties....

I don't hold with furniture that talks.
