| S/W. (Hs{Lord Ernest Hives - Chair}). X2028 CxB/CM12.6.25. Will you kindly let me know whether you have, in the past, experimented with under-slung semi-elliptic springs on the 40/50-H.P. Rolls-Royce, with a view to deciding whether that type, or the present system of canti-lever suspension is the better. We are anxious to convince a customer of ours that he cannot do better than have the existing system, although he is strongly in favour of the under-slung semi-elliptic. Cx.{Major Len W.
