| 1113 To GWH.{George W. Hancock - Head Chateauroux} at Kingsbury. c. Rm.{William Robotham - Chief Engineer} BY/Mtn6/N.22.9.38. Particulars of Cylinder wear during August. We thank you for the chart giving the above information. It is noted a rebore was necessary on chassis B.103.GP. after 18,449 miles, and we consider this would be a good case to try "Arctic" oil, as presumably the car will not have done a big mileage since the re-bore in August.
