| -2- Rm{William Robotham - Chief Engineer}/GR.{George Ratcliffe}12/JH.10.6.38. A second modification applicable was that of fitting the leather accelerator pump piston for service complaints of poor acceleration, (see our letter Rm{William Robotham - Chief Engineer}/GR.{George Ratcliffe}12/JH.26.4.38). The third consists of the counterbored choke spindle bearings ECD.648. This completes the list for 30 HP. carburetters. We hope this makes the position clear between Wraith and 30 H.P. carburetter modifications. In reply to your letter of the 8th inst. we agree to locking the throttle screws on all models by means of solder. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
