Hi

When we moved into our house we found that (for some reason best known
to themselves) the vendor had removed the (ceramic ?) part of the
bathroom taps that say "Hot" and "Cold". The taps are "edwardian" in
style. I'd like to get hold of replacements. Can anyone guide me as to
what these parts are called (indexes springs to mind..) and where I
might get hold of some ?

Thanks

Paul
