This is a set of three items. I am offering these items as reference materials to understand the background of the CB750 Four at the time of its release, and to be useful for maintaining the CB750 and other models listed in the manuals, which are now classic cars. The three books have age-related wear and tear. There are no missing pages. There are no markings in the text. Other notes: New Car Explanation Manual: A delivery receipt is attached to the inside of the back cover, with the date 1980.5.24 written on it. New Product Guide: Markings and stamps on the front and inside back covers, and a stamp on the back cover. I hope you will purchase these as reference materials for maintaining classic cars. #CB750four #HondaClassicCarManual #HondaServiceManual #UsedCatalog #InstructionManual
