Vespa flyscreen for gts, genuine part

Large vespa flyscreen, genuine ,vespa brand. I bought the wrong one. This is for a GTS and my wifes bike is a primavera, so the brackets don't fit. This is a genuine Vespa screen and they are around 250 euro new. Sadly I dont have the receipt so can't return it to get the correct one. I did fit it but it sits too low on the primavera and won't let the handlebars turn so it hasn't actually been used. It's no use to me so im selling it for 120 euro o.v.n.o, less than half price. I can deliver it , but that will incurr a small fee depending on the distance Scooter, moped, piaggio,
