I don't see how you can do a proper test without a visual inspection of
the connections... And I've yet to see a moulded connector that provides
a proper strain-relief for the cable.

The cable mounted section looks like a normal 'cold condition' _socket_,
but there are 3 round pins sticking out of the face of it (where the
socket holes would be). The chassis part looks like the normal plug
(recessed into the panel, etc) with 3 holes in it in place of the normal
plug pins.

I've seen it used on some German stuff (some kind of mains controller
thingy). I don't think it was a custom connector. It may well be fairly
old, though

No, certainly not that one, and not any of the normal Bulgin connectors.
