Contacts for Cross Steering Tubes and front axle controls. Bentley old type Cars use low carbon case hardened contacts for all their steering couplings and get a very small percentage of trouble, wear is almost unknown. Could not this be applied to our own cars and cut down wear which is experienced. Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} | ||
