| To B.J. from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} c. to CWB. c. to C. c. to PN.{Mr Northey} c. to H.{Arthur M. Hanbury - Head Complaints} x8430 Hs{Lord Ernest Hives - Chair}/Rml/LG11.11.26. STEERING. x8450 x8420 x8430 With reference to CWB1/LH{Mr Haworth}9.11.26. Our objection to the 1500 lbs. springs and the old type axle is that owing to the heavy steering with this axle, the 1500 lbs. springs produce a somewhat spongy feeling when combined with the .720 worm ratio. We consider that the present steering is the best compromise for the majority, the exceptions who complain can be satisfied with the 1500 lbs. springs. The last 10,000 miles test in France was run with the new type axle and the 1500 lbs. springs in the side steering tube. These springs will therefore come on production with this axle unless in the meantime a better springs is evolved. Balloon tyres on the old type axle create a special case as they are liable to increase road shocks at very high speeds: 1500 lbs. springs can be fitted to such cars if it is known that the owner is a speed merchant. We do not agree that the 720 worm and 3500 lbs. springs cannot generally be considered as satisfactory for road shocks. 8-EX car was run 10,000 miles in this condition and was admitted by everyone to be relatively free from this complaint.
