Time to revive an old thread [Linked Image]

I have one of these adapters, made by Kopp.

[Linked Image from i.kth.se]

Four of these plugs are simple enough to figure out: British 13A and 5A combination, Australian, American 15A (unpolarized) and European (Swiss).

The fifth is a bit odd. It is supposed to be British. It has two 16 mm long round pins (5 mm dia) on 16 mm centres. I suspect that this is an old ungrounded 2A plug (BS 372???) but I cannot for my life figure out why they would put something so obscure on a travel adapter. Could anyone help me out?
