Not sure how to send a pm . only just joined the forum and a new twizy owner.
It is the original Renault top cover. But for some reason they don't sell it in the uk (I contacted several Renault dealers). It is on the german Renault website though.
Please note though it only fits the twizy with the doors, i.e has the wing mirrors are offset.
here is a picture.
I paid £165 which is a saving on the new price. just looking to recoup my money really.
