I think you mean this? I used to make these for a few members on this forum, I still have the mould, which is a two-part item. Here are some photos of the ones I used to make and a couple of one fitted to a members bike, there is also a photo of the original item from the Ducati catalogue. They have always been very rare and I doubt that you will find one now, I had two originals one being used to make the mould and they sold for very good money even years ago. I think the original price was about £127 in the late '90s etc.
