Remember a country named East Germany? Gothic lettering very probable. Had radio companies. Iron curtain frontier. Full of Russian troops. Not much imagination needed for a possible scenario of being made there after copying a Philips and making it into a Russian ship.

I tried to enhance the image posted earlier of the logo. The first letter appears gothic and I think may be an S. Anyone get a spark of recognition?

Can't make out a thing, but using a rectangular black ink stamp on the chassis instead of some sticker reminds me of the SABA Permadyn 5 Ω ranges. Something German might be at play after all.

Are you shure it is a permanent-magnetic speaker? Pre-war radio sets often did use electro-magnetic speakers, which generated the magnetic field with a second coil on the speaker - and this coil acting as the plate supply choke at the same time. The membrane coil usually had 5 Ohms at that time. Just look if the speaker has 4 separate connections - how many wires are in the cable?

I dug out the Philips this reminded me of, and i think i can safely say the detail is not the same, so not Philips.

But the coil was where the magnet is. This is not a field-coil. A picture of a field-coil attached.

Any chance those are Telefunken's?

It's not a field coil, it's a magnet - and pretty strong.
The speaker has two terminals and they're soldered to the wire - nothing abnormal.
I'm almost sure it's not Telefunk - they usually had very clean designs, and the logo doesn't looks like telefunken at all. I'm also not certain about DDR: gotic letters were used by Hitler so after-war logotypes avoided that. It may be a pre-WW2 German thing. Did they have premanent magnets before 1945? Because I've seen too many field-coils from 40's.
