| TO FN. FROM R.{Sir Henry Royce} ORIGINAL R1/M14. 12. 23. c. to CJ. c. to HS.{Lord Ernest Hives - Chair} c. to BY.{R.W. Bailey - Chief Engineer} re. "MILES PER GALLON" INSTRUMENT. X3896 Referring to your PN{Mr Northey}14/DN121023., I do not consider this scheme would be a success. It is too complicated and delicate, and impossible to obtain and retain accuracy. Also it would probably stop the car. I could not recommend that we fit these to R-R cars. I return the papers herewith as requested. R.{Sir Henry Royce} | ||
