Re: Another unusual plug and some other questions
Hi Robin, I may be wrong but I don't think anyone has ever written a history of mains plugs and sockets (but try querying the IET library, or post a request on the IET forum).
If you are lucky try googling the various electrical companies and see if there are copies of their caralogues on line. The BVWS did a repro of the Brown Bros catalogue some years ago which had a few illustrations in.
You can also look at old trade magazines as well as books such as "Practical Electrical Engineering". These were often in many weekly parts and assembled into a 4 or 5 volume set.
Happy hunting, Ed
