Please address all replies to the Company only and quote reference as under: Broadway Court, 8, Broadway, Westminster, London, S.W.1. 17th December 1931. W.A.Robotham Esq. Messrs Rolls Royce Limited, Derby. Dear Mr.Robotham, Many thanks for your letter of the 16th instant. I hasten to write to you at once as I was sailing in the "Homeric" but the sailing of this vessel has been cancelled, and there is no other boat sailing other than the "Berengaria" if one is to arrive in Detroit by the 25th instant. I am very much indebted to you for your criticisms, and agree entirely with what you say. The only point upon which there seems to be some difference of opinion is in regard to the braking, but even here there is not very much in it, as in order to get our A.B.K. co-efficient the weighting wants to come out to approximately 65/35, and, when the car is full the total weight of the passengers is somewhat forward of the centre of gravity, and therefor this proportion is reduced. Unless, therefor, we start off when the car is empty with this higher loading on the back wheels, we should not even get 60/40 when she is full. we do not seem to have got into trouble with stability at speed, up to the present, but our speeds have not exceeded about 85 m.p.h. I think it quite possible that if and when cruising speeds are raised to 120 m.p.h. that we may have to | ||
