Re your Kopp adaptor.
I could be wrong, but I think that is the same size as you would find on UK shavers & electric toothbrush adaptors, but with part insulated pins.
The only place you would find such a socket in a modern UK installation is the isolated shaver socket used in bathrooms. But bathroom shaver sockets take international plugs.
Could be some other countries (old British colonies) still use that type of socket.
