For sale here is the owners manual for the 1980 Ferrari 512 bb. All information is factory material, in PDF format. The manual is in English and multi-language, and contains 119 pdf pages in total, maintenance schedule, operation instructions, specifications, and much more.
The advantage of having the owners manual in PDF file format is that you can quickly search a keyword, or jump to a specific section to find what you are looking for. Also, you can print out a section to take with you to to the shop, and make notes on them (you probably wouldn’t write on the factory book manual).
