| 500 a. {Mr Adams} Rm {William Robotham - Chief Engineer} /GWH {George W. Hancock - Head Chateauroux} /HFH. {Hoppy F. Hamilton} from Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} Rm {William Robotham - Chief Engineer} /Gry {Shadwell Grylls} 17/R.6.1.37. As regards your memo and report on 22.G.V., there appears to be some inconsistency about the mileage done by the deturbulated cylinder head. You say that this was fitted at 24,000 miles; further, you say that after 8,331 miles the valves stuck, and after this was put right no further trouble occurred during the following 8,000 miles. This would appear to show that the deturbulated head did 16000 miles, but as your first paragraph shows the total mileage of the car as 38,144, there appears to be something wrong; furthermore from a letter you wrote to us it appears that the valves stuck after a mileage of only 1925. There is no reference in the Daily Report to the valves sticking at all, and only this one mention of it in a separate letter. As we want to send out the memo to Sg. {Arthur F. Sidgreaves - MD} etc., we wonder whether you can clearup this point. Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} | ||
