The plug description is much better than the other ones I've seen.
What about adding the polarized NEMA plug to A?
Picture D answers the old question whether there are BS 546 plugs with the cord emerging straight.
Some E plugs I've seen (old "French only") were not round but shaped like a triangle with rounded corners.
The "shaped C plug" is called "contour plug". It has 4.8mm pins and is shaped like a Schuko plug.
In Italy there are also wall receptacles that have an Italian 10/16A and a standard Schuko receptacle side by side. Lots of equipment in Italy is sold with Schuko plugs, hence lots of adaptors. Really looks like the good 'ole italian plug is going down the drain in favor of Schuko!
Australian sockets are always grounded, but plugs aren't necessarily!
Italian 16A plug has 4.8mm plugs, so you can't plug contour plugs into an italian receptacle (frequently heard girls yelling about not being able to use their hairdryers). As a matter of fact our room at a Torino Youth hostel had a receptacle which would _only_ take 16A plugs! Imagine the cursing of 4 people wanting to charge their cell phones!
