Rolls-Royce Phantom I (USA), Owner's Manual for the Phantom I build in Springfield, Massachussetts (USA); complete set of photocopies (bound); instructions for running and maintenance of what is called "Springfield Phantom I".
This is not the 'condensed edition' - although that is quite useful - compiled during the 60ies by the Rolls-Royce Owners' Club of America but the original 130-pages compendium edited by the US-factory in the 1920s.
