BALLOON TYRES - 20 HP. f4565

Further to our Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}2/LG19.3.27. We omitted to mention in this note that friction must be fitted either in the pivots or in the cross steering tube on 20 HP. cars which are equipped with balloon tyres. If this is not done there will be serious danger of low speed wobbles.
