Some 20-25 years ago, I helped to unload a (few) container load(s) of WS19 sets in transit chests. I don't know a lot about radio's but they looked like complete sets, ready to use as you describe. They came from Greece and were imported to Holland by a dealer. Back then
Gerard Deibel was the specialist working on these sets, I guess he's able to recall what they were exactly.
Back then, I saw so many 19 sets that I lost interest....
