Go to Ibstone common, Just off Jun' 5, M40 and watch the Red Kites, I loved it when I lived that way.I looked up the website and Vincent does not figure. It looks like a dust cover. I eventually went down the Oxford products route and purchased a cover with a soft inlay and water proof covering but essentially it had a elastic rim around the base so the cover hugged the bottom of the wheels/engine giving a nice seal so that if it rained for days i. e. May the chrome and other parts were well protected - so I am enjoying the leafy lanes of the Chilterns at the moment keeping to the 40mph limit!
