Mr. Lidsey's report on Phantom experimental cars says that Watford magnetos are quiet, while Lucas are noisy. That is different to the report by EFC., who judged the Lucas the better. You will remember that I did not wish to change to Lucas, principally for reasons of reputation, so that I am very pleased to hear that we are not forced to do so by any technical reason of silence or efficiency. The Watford magneto has several features which are preferable to the Lucas. (They add to the cost, but the price is now quite satisfactory - i.e. commercially O.K.) It is understood that the sleeve type is better for the 20 H.P. AERO. Apparently Thomson-Houston are doing well on aero engines, and there is no reason for changing, so unless I hear to the contrary we shall be getting along with other work. R.{Sir Henry Royce} | ||
