Just stumbled across this thread. I can’t believe other folk find this stuff interesting too.
When i was little in the late fifties early sixties my first task when visiting a house with family was to investigate a houses electric sockets! Every house was different back then. I clearly remember my grandparents had a two pin 15 amp socket in their lounge, they also had a drawer full of old electric plugs and sockets. Needless to say i am now 62 and never throw away an interesting plug. Or charger for that matter. I have a drawer full of continental, US and australian mains leads, kept - just in case. Also have a ton of audio, video, telephone and aerial cables....
Crazy, but clearly i am not alone!
