I'd like to see some supporting data for that litle outburst.

As late as the 1960's London had FOUR different electrical systems with
different voltages and plugs.

Are you sure about that? There were several different socket outlets still
in use - 3, 5 and 15 amp all in either two or three pin. As well as some
odd types as an alternative to the common 13 amp plug - notably D&S and
Walsall gauge, sometimes used in council housing estates. But I think the
voltage was standardised some time before then.

As late as 1989 I bought a clock radio
in London that did not have a plug on it. You had to buy one that
matched your outlets.

Yes the requirement for a fitted 13 amp plug hasn't always been.

As lightbulbs were mostly the same size around the world a friend of
mine who traveled, carried an adapator that screwed into a lamp
socket and had a standard U.S. outlet instead of the bulb.

Heh heh - in the UK the bayonet fitting is the common one for GS bulbs.

I have one that is like that but it has another lamp socket
on the top and two "euro" two pin outlets. I assume that they
are highly illegal in the U.K. now.

Perhaps the majority of the sort of things you'd want to plug in to that
are now double insulated so require no earth.
