| HS. {Lord Ernest Hives - Chair} FROM R. {Sir Henry Royce} CONFIDENTIAL RO {C. C. Rose - Export Manager} /W6.12.32. Sent off 9.12.32. 82677. C. to [text obscured by strikethrough] PETROL PUMPS. Referring to HS {Lord Ernest Hives - Chair} /RM {William Robotham - Chief Engineer} 13/MA21232. I am very pleased to hear that you have some more promising material for the petrol pump diaphragm. You will remember that I never had much faith in the A. {Mr Adams} C. material, and I had the impression that the electrically driven petrol pump had a corrugated diaphragm (sylphon type). I should be happier if we could have the same. R. {Sir Henry Royce} | ||
