Default Re: Any other plug collectors out there?

I read somewhere that the original coloured sleeves on the pins was introduced by Duraplug who protected (patented?) it so no other companies could sell such plugs. Certainly Duraplugs which such sleeves exist.

But I was surprised when I bought a box of new Duraplugs a couple of years ago (from RS, so I think they are genuine). The sleeves were black. The (IMHO excellent) colour coding is no more.
