Speciale Original Books

Can anyone tell me what books would have been included from the factory for my 1993 348 Speciale? I have an acrobat version of the ’93 348 owners manual but are there any other books that would complete my binder? Was there any special documentation that came with the Speciale cars? If so, any thoughts on where to obtain them? I check eBay periodically but have not had much success in find the correct books. Thanks for the help.
