X537 HS{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/JH.8.4.36. 25/30 HP. Transmission. Referring to Mx.{John H Maddocks - Chief Proving Officer}1/T.4.8.36. We should like the propeller shaft damper bringing into production again on the 25/30 HP. as soon as this can conveniently be arranged. It will be remembered that when we deleted this damper we left the head of the shaft on the car, as we anticipated that we might wish to revert to the damper. From experimental results in France, and from MX{John H Maddocks - Chief Proving Officer}'s. tests we now find that this is desireable.
