| X777P Pt.5/FM-20/6/28. Hs. {Lord Ernest Hives - Chair} Derby. C. to Whr. {Mr Wheeler} London. I should be very glad if you could inform me by return how the present New Phantom(Codename for PHANTOM I) with 4 wheel brakes compares with the old Silver Ghost(1907 40/50 historic RAC 15,000 miles trial) without them as regards ratio of H.P. to weight. If you can give me this in various stages showing S.G. with front wheel brakes and also long chassis and standard chassis, it will be useful and most illuminating. The same applies to the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) and India(Production 20 HP. with 4-speed box and Front Wheel Brakes)n models of the 20 H.P.
