The Ducati owners website has a blog where sad internet / ebay trawlers like me note on the site any interesting bits coming up for sale around the world. As an example, I purchased yesterday, off ebay italy, a disk braked/borrani rim front wheel, which just leaves me the rear to find now.
What i did see, but don't require, on ebay Germay, is a 'Valentino type' 2 into one exhaust in excellent condition.

Just wondered whether others would be interested in contributing to the blog? (many people dont realise that ebay is by country, and that ebay.it has LOADS of morini stuff on it. To search against other countries, just add the country initials after ebay ie Germany, known by Germans as Deutchland, is ebay.de
You'll also find a fantastic translation tool on your google search page where you can cut'n'paste the ebay description and with will (roughly) translate it. Of course it's invariably the case that all foreigners embarass us by their knowledge of English so they reply easily in general.
