| Messrs.Rolls-Royce,Ltd., Date 29.7.30. Page 3 If the unit were placed sufficiently close to a baffle, we have no doubt that pumping with the fresh air available, would be sufficiently vigorous to do away with the necessity for the hand pump, and as soon as you can return the unit to us after your inspection, the writer hopes to make some pumping trials, using a very volatile spirit to give us the desired results. Assuring you at all times of our best attention, We remain,dear Sirs, Yours faithfully, H.M.HOBSON,Ltd., T.P.Searight Joint Managing Director. | ||
