ECN Forum Forums Photo Discussion Forums Electrical Nostalgia Old Bayonet Adaptor & Plug (UK)

I have a variation of Trumpy's bayonet adaptor, designed to convert the bayonet to a 5amp two pin socket. There are the remnants of a retention cord, so I think it was originally attached to a mating plug. The appliance could thus be used in a wall socket or light socket as available.
The other pictures show a CLIX plug, using springy brass cotter pins as connecting pins and also to attach the flex. The serrations inside the cover do "click" over the heads of the cotters as it is screwed down. The natural spring of the cotter pins ensures a good tight mating in a socket; and a lot better contact than some modern plug/socket arrangements I've encountered ! I consider this a particularly ingenious piece of design for its age.
I'm guessing they date from about 1930 (?).
