Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair}1/MS.23.11.31. X4562 BOSCH DYNAMO. With reference to the attached, we are arranging to fit this dynamo on to one of our chassis. We consider that we are now doing as well as we can expect with the third brush machine, and that any further improvement needed will have to be obtained by voltage control generator. Undoubtedly the popularity of the third brush machine is its cheapness. Bosch for the high class cars always fit the voltage control generator but make a third brush machine in order to compete on price. Hs.{Lord Ernest Hives - Chair} | ||
