| Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to BJ. SG.{Arthur F. Sidgreaves - MD} 4038 R4/M24.4.28. PETROL GAUGES. E.4038 X.3896 Is it necessary for us to have dashboard petrol gauge as standard, because it - (1) Involves more pipes, 2 more upon the top of the tank, and one the length of the chassis. (2) Makes more instruments upon the dash. It is therefore costly, and involves responsibility about reliability. R.{Sir Henry Royce} | ||
