| Copy - 2 - Letter from Hans Detlof von Winterfeldt. Layout of the engine is fairly neat but very inaccessible; for xx instance to remover the steering column it is necessary to remove a complete cylinder block. The capacity of the autovac tank is extremely small carrying only 3 litres benzine to supply the 2 carburetters." I hope these informations will be sufficient for you. I have heard people complaining about the exceedingly heavy petrol consumption of the 12-Cylinder model. Yours sincerely, (Sgd) von Winterfeldt. | ||
