I have an old anglepoise type lamp. The bulb holder has finally given up the ghost. I wonder if any one knows where spare parts for these lamps can be found. I have searched the web and so far drawn a blank. It is a pity I cannot post a photograph of it.
I suspect it is not actually made by anglepoise originally though its design is generally similar at least my searches reveal nothing similar. But here is a verbal description.

It has a very heavy square black base with two springs on each tier of the arm. The lamp shade is black and unlike any anglepoise shades i have seen being shaped like a simple tall wine goblet. It has the switch on top. The shade and switch mechanism are attached to the top of the arm by chrome or stainless steel ring.

Any thoughts gratefully received.
