| X 3281 EH1/LG26.3|18. Exptl: Dept. Rolls-Royce Ltd. Derby. 27 March 1918 C/o Davidson 36 Willowbank St.{Capt. P. R. Strong}, Woodlands Rd., Glasgow. Dear Sir:- Re. your letter of the 26 inst., I am forwarding drawings on for your inspection immediately. There are a few slight alterations necessary which I have already made on those that are finished, for instance I have made the throttles bear all round instead of at two points only. This prevents any possible chance of any air finding its way into induction pipe without passing the jet. The shape of needle is also different to drawing. It is something similar to sketch shown here This makes it very efficient for starting up & slow running. P.T.O. | ||
