Yes, there are quite a number of versions of the Giulia Spider/Veloce owner's manual. Publications were issued in Italian, English, German and French from late 1962 - 1965 with some additional revised versions having been issued as well. Such is the case with your current copy which I believe to be Pub. #1040R (the letter R for revised) published 8/65 with 1000 copies having been printed.
I have copies of #838 (English, 9/62, 2000 copies), 838R (English, 12/63, 1500) and 1040 (English, 2/65, 1500) in pdf format I could send if you'd like.
I've also compiled a list (a work in progress) of Alfa publications I could send as well.
BTW, the number of copies of a particular manual and the number of vehicles produced are not related.
I probably do. I know there are several emails from people about their Veloce's that needs to be entered into the register as I posted this to the BB. If there are any questions, I will get back with you. Thank you for asking.
