With reference to By.14/G.18.8.39, we are very concerned about the fact that unless we take advantage of some of the economies which we have established recently, the material cost of this car is going to come out in excess of B.V. The reason for this is that the Rolls-Royce radiator is more costly than the Bentley radiator, and the movable radiator shutters are, of course, a more expensive item. We recommend that the following features should be incorporated in the Ripple specification:- (1) Monichrome camshaft running direct in the crankcase. We have had complete success with this arrangement so far. There is no reason why deleting the bearings should give trouble, in any case the bearings we have been using in the past for the camshaft have been aluminium. (2) A.C. air silencer. We have now developed a satisfactory air silencer which is half the cost of the one made in this Factory. It is only a question of getting a satisfactory finish, about which there should be no difficulty. We recommend that this should be adopted. (3) Exhaust System. We are sure that the Burgess system as now modified will be satisfactory and this should be adapted. | ||
