| -2- Hs {Lord Ernest Hives - Chair} /Std.21/KW.23.10.35. We should like to have your opinion on (1) your design for the smallest size of bellows practicable, and (2) the length of bellows necessary to give the rating quoted above. We should very much like a reply by return of post if possible, as we cannot proceed with our design until we know the approximate overall dimensions of the thermostat. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
