Interesting article...from the illustration it does look like the plug pins are of round section, rather than flat. It was common in Australia up until the 1950's to still be powering appliances from a light socket. Often there was only one power point in the house and that was for a fridge. Smaller appliances like radios and shavers were plugged into a light socket by means of a bayonet plug. A bayonet double adaptor was available if the light bulb was required at the same time.

We still are using those plug clusters and other such things to plug appliances into lightbulb fittings. Sold in every hardware store (and a lot of dollar-stores also!).
And that's something that always amazes me! Of course we have had that stuff too, but it disappeared from the stores around 1960! No way you could sell something like that today! I guess it could end the store owner in jail. Haven't even seen an old one really used in my 20 year life... apart from the one I had as a kid and used to power my cassette recorder from the desk lamp (my desk only had one ungrounded socket next to it, one of the few my dad hadn't rewired because they already had PVC wire, so I was pretty glad I had two additional ungrounded sockets...) but even as a 6-year-old I took great care the bulb wouldn't burn the cord!

Ragnar, you gotta remember that quite a lot of consumer electrical accessories are sold here without any safety agency testing - some of them even have forged certification seals.
I could show you dozens of extension cords, plug clusters, attachment plugs, sockets, etc. that bear no markings at all. Most, if not all, of this stuff is manufactured in - and imported from - People's Republic of China.
Sometimes, also, the quality of the legitimately marked items is so shoddy (socket contacts that grip so loosely that the plug just slips out) that you wonder how they ever got the certification seals.
