| To Sg.{Arthur F. Sidgreaves - MD} From Hs.{Lord Ernest Hives - Chair} c. to Mor. (58) 40 Hs.{Lord Ernest Hives - Chair}4/MJ.28.3.30. 10,000 MILES ON 20/25 CAR. Replying to Sg.{Arthur F. Sidgreaves - MD}3/227.3.30. We anticipate that the 25 HP. car will need decarbonizing after 10,000 miles. The old 20 HP. needed decarbonizing after that amount of running. We are arranging for Rm.{William Robotham - Chief Engineer} to go to France on Monday to try 14-G4 and check over a number of the results. We are still having a certain amount of difficulty with the exhaust system and he is taking with him some modified parts to be fitted. We will let you have a report when he returns.
