I have just lucked out as the Americans say in getting the above book locally, second hand. It is very good and covers my W108.057 in detail plus many other models in this era. Others may be interested in it too, if it is available elsewhere. There is a lot in here that the Haynes equivalent, which largely covers the pagoda and the M130 mechanical fuel injection engine, does not have. This book covers the whole car too, not just the engine.
