There is a parts list for the 3000ME detailing the part number and origin of many of the outsourced parts used by AC, which has been compiled over the years by various owners. It is included in my article on Buying, Running and Restoring and is published on the 3000ME page of this site. If such a list exists for other models we will of course publish it but it is up to owners of a particular model to put the information together and check its accuracy. So far there are NO 428 technical articles on the 428 page. An enthusiatic Mk IV owner compiled the entries from dkp_cobra's rebuild and that is on the Mk IV page. If anyone wants to do a similar thing for some of the Frua threads, please go ahead, send them in and I'll put them up.
