Might want to go over to
http://www.ducatimeccanica.com/ and see if you can find it there. Otherwise, just send the jpeg to Rene Waters who runs the site. Someone there will be able to identify it. My expertise is limited to Laverda Triples, and some later Ducati desmo's, not the bevels. You could also try
http://www.eurospares.com/other.htm run by Michael Moore for an incredible amount of information and archive photos. No doubt, this one will be there.
