Mostly, pop-up mechanisms are not going to fit in a flip toaster.

I'm reasonably sure that it is illegal in the UK for a business (and this includes charity) to sell an electrical item that does not conform to current standards, but sometimes you can get old ones with the flex cut off and do your own restoration if you simply like old things (and why not, I'm an old thing myself).

In the EU old amplifiers with bulgin sockets must be converted to new IEE connectors of they are to be repaired by a business.

I am doing this toaster first because it is so pretty - but still am agonising whether to go for a 3-core installation (with added earth, then I could use it with an ELCB at the socket and maybe live to tell the tale) or keep it original with the 2-core and believe that it hasn't killed anyone yet so why should I be the first? Those mica washers worry me.

After that I have some nice old radiant electric fires, including a flicker effect mock log one.

I did the standard and table lamps long ago - with modern wiring throughout and where possible modern lampholders, but getting the modern bits inside old brass fittings and removing carbonised bakelite to get the old bits free was quite a game.
