Thanks!

I was glad I was able to buy some links that went with it, though I hadn't expected the black links to blend well too. This chain is more solid and heavy than the original one, which was simply a strand of bronze-coloured curb-chain.

I've got a watch chain, my great-grandfather's I think, in two colours - I'll try to remember to look for it and take a photo to show you.

That would be interesting to see how they did it, yes.
