I think Theo puts these together. he has 3 for Ferrari for sale on Fchat
Hall sells reproductions guides and Silvestro has NOS Warranty cards and specifications on eBay fro time to time. The original owner guides are quickly identifiable as they have velum pages showing lubrication points (that the reprints don't). I just hope this buyer did get an ORIGINAL guide.
Editor's Note: I don't think Ferrari chat allows lurkers, you have to log-in to view their content.
