X.8420 X.5420 The second and present standard on the Phantom, which is also standard on the American chassis, has proved a decided advance on the first front wheel brake axle. The reasons are too numerous to be given here. The result is that we are making the 20 HP. to similar physical quantities and the same general design. R.{Sir Henry Royce} | ||
