| -2- 11th. February 1938. relative to length of bellows in position (when cold) has been left to you. If possible we would like this arranged so that in case of failure, the free position of the bellows is such that the valve is not less than .125 off its seat. In any case we would like your remarks on this subject. Yours faithfully, for ROLLS-ROYCE LTD. | ||
