Google copper lamp chain.

You know, I tried that before posting; several times in fact, and only got sites that happened to have both copper and chain, but not together. But on your advice I tried it again, and lo and behold I found one. I have to say the photo does not inspire confidence (looks rather brassy), but will give it a try.

So thanks,
