| To Sg. {Arthur F. Sidgreaves - MD} From Hs. {Lord Ernest Hives - Chair} No.4/MJ.3.9.30. X7230. EXHAUST VALVES. X.4011. X.4488. X.7230. X.5230. Replying to Sg {Arthur F. Sidgreaves - MD} 18/E2.9.30. We do not propose to be pushed into any alteration of exhaust valves. R. {Sir Henry Royce} pressed us to use Ostenetic Steel which landed us into trouble and a considerable amount of scrap. We do not remember ever having a case either on a car engine or an "F" engine of trouble with the exhaust valves, except the one reported on 24-EX. In view of the excellent record of exhaust valves we shall want to do many 10,000 miles before we are satisfied with any new design. Hs. {Lord Ernest Hives - Chair} | ||
