Ditto what Nick said.I do like siphons myself.I've always fancied doing one of those siphon c's myself.Are they sraightforward ?Even the Dart Castings platform seat looks superb.Top modelling.
I used the ID ones on mine.See my layout for them .I think they're available in two width sizes as well.I was pleased how mine turned out.Don't use the Peco ones please !
