Gaiters. - These are standard and included in cost of chassis. (8) Cord tyres and increased vibrations on closed car. 40/50 type. It is necessary that Sales Dept. should try and get - (a) Customers to use low tyre pressures, this being more necessary with the present cord tyres. (b) Suggested that a plate be put on the car showing the maximum load and tyre pressures for that load. (c) A specimen of this plate to be sent to London as soon as possible, stating where it is to be placed. (d) It was pointed out that the present straight-sided tyres accumulate rust between the ring and the wall of the tyre. BY.{R.W.

(c) As in giving demonstrations the performance of our cars often have to be compared with the performances of other makes of cars, 14 tooth axles should be used. This should include all cars used for demonstrating purposes, including our own, our agents and our inspecting demonstrating cars. (10) Battery Support on Goshawk. BY.{R.W.
