I've had a good look in and out and can find no markings - I'll keep on the look out otherwise I'll replace the whole lot and get something more standard next time.
Thanks for your helps.
I've had a good search on google and trawled quite a few DIY places but they can't find one that matches.
It's not a D shape - it's more of a V shape seat which is making it hard to find.
I've looked every where and can't find it due to it's odd shape.
Does anyone have any idea where I can get one of these seats? (I lost the receipts etc so don't know model/make)
Cheers for any help
