X.5431 X.8425 X.9431 X.5425 Regarding the damping friction of the balls of the cross steering tube, 1200 lbs. spring load on the Phantom and also proportionate on the 20 HP., this has proved a decided benefit. It has not caused excessive wear, as shewn by 7-EX during its last 10,000 miles in France. The reason I prefer it is that it avoids rattles. R.{Sir Henry Royce} | ||
