| 200a Rm{William Robotham - Chief Engineer}/GWH.{George W. Hancock - Head Chateauroux} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}5/R.17.2.37. We think that 3.B.IV will be ready to come out at the end of this week. One of the features on this car is fixed radiator shutters, combined with thermostat regulation of the water temperature. Rm.{William Robotham - Chief Engineer} wants Std. to bring the car to Chateauroux, and there to carry out the usual towing testing with 6.B.IV. as a comparison to find out whether sufficient air gets through the radiator. Steadman at the moment is off with 'flu'. If, therefore, he is unable to bring the car to you at latest by Monday or Tuesday next week, I will get in touch with you and ask you to meet it at the Coast on your side. With regard to 35-EX, I gathered from your telephone conversation with Rm.{William Robotham - Chief Engineer} that if you have to choose between one roll rod and the other, you prefer to have the back one. Does this mean that you will be happy about standard-ising the Wraith wheel movement without a front roll rod ? With regard to the propeller shaft fouling the 3rd crossmember, this is likely to happen when the rear roll rod is disconnected, because the levers of the rear roll rod act as re-bound buffers.
