Even after the 13 amp

for that - let alone the older 2, 5 and 15amp in both two and three pins.

I wish I had kept for interest sake a plugtop I found some years ago.

Istr that it had two round pins about the same size as the old 15amp
and an a rectangular earth pin as fitted to 13 amp plugs, or possibly
it was 2 rectangular and one round.

The wonderful 'Fitall' plug could probably have faked them both.
