I have seen similar plugs with vertical pins on one or two sets in the past, probably to connect to a built-in aerial system in a house or apartment. But those would have only fitted into a mains socket if one twisted the pins.
And they say old radios can be unsafe... pffft, I say. Collier and Beale built in a nice slow-blow coiled fuse just in case this ever happened, and I bet the rest of the radio is just fine... although the undies of the person who plugged it in might be a different story
There are no personal problems that can't be solved with the liberal application of high explosives

Yes, I certainly do. It's very safe. I have made a large number of email enquiries (maybe a dozen, or more) to various places around the world to try to locate a roll of Litz wire. One British company (who I initially had a lot of faith in), advertises what appears to be almost the exact wire I need, but they have failed to reply to 4 of my emails to them. I am still on the active hunt for a roll of Litz wire, and your coil winder has not been forgotten or overlooked.

I had hoped not. I know I have had it for a long time.
You have mentioned unwinding an old coil to 'score' the wire from one of them, but those coils are as scarce as hens teeth as well. The faulty coil in the Gulbransen radio I have here has a former that would be the best part of 1" in diameter (7/8" anyway), and looks like it would have about 200 turns on it. That alone is a lot of wire. A mate of mine dropped in an old B&W TV line oscillator coil, but that wasn't suitable either, as the winding was doped in something like epoxy. I still live in the hope of finding a supplier of a roll of 7 (or 13) strand Litz wire. It will be 'out there' somewhere.
