| L1729a G.W. Hancock Esq., Hotel de France, Chateauroux, Indre, France. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}5/KW.17.11.34. Referring to your Daily Report of Nov. 14th, we note that you are experiencing a certain amount of noise with the hydraulic tappets. Naturally as we are just about to go into production with these we are somewhat concerned by your remarks. We should like to have all possible information as to what has happened to these tappets. We note that all the adjustment has been taken up on your brakes. Do you want us to do anything about sending you out new linings ? You say the water pump drive rattles, here again we are interested because we are proposing to use a chain drive on the Wraith. Is the rattle due to a faulty sprocket or worn bearings in the pump ?
