You want to pay £200 + for all the jap crap internals that go in these ,go for it .You want the romance of doing one up so your bathroom has that post Victorian look about go for it.When your sitting there logging on /off you will be scratching your head or ars…why you bothered.Cosmetically the externals you can do whatever you desire with…no end ,and can look truly fantastic.I once found one with a vented lid ??the only one I’ve seen.Ive done 2 of these up I’m my time and there’s an order of importance ,brackets ,lead ,and wood the rest is just not worth it .No one will ever ask how it works ,what kind of flapper or valve is in your cistern,I know .Best ones make fish tanks or planters .All in my honest opinion I could be talking crap…I just want back what I payed for this one 🙏🙏🙏
