| 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 PhantomCodename for PHANTOM I with 4 wheel brakes compares with the old Silver Ghost 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 and Indian models of the 20 H.P. Pt. [illegible signature] | ||
