Brand new toilet (East Acton W12)

Giving away a brand new back-to-wall toilet. Arles rimless couple coupled rimless fully closed back pan.
PAN/BOWL/BASE ONLY.
This was fitted as part of our bathroom refurb, but found to leak because of a manufacturing defect on the waste spigot which has a ridge causing a leak from the waste pipe.
The supplier replaced it and said I could just dispose of the original, but I can't bring myself to just smash it up. I suspect that with care, the ridge in the spigot could be ground down and that if so, a proper seal could be had, maybe in conjunction with some 'Plumber's Mait'.
NB: bowl only, needs a cistern.
Very heavy, so suggest a 2 man job to collect.
Collection only from East Acton, W12.
Serious enquiries only.
