| X 4342S. COPY OF LETTER RECEIVED FROM:- S. SMITH & SONS LTD., CENTRAL WORKS, EDGWARE ROAD? CRICKLEWOOD, N.W.2. Our ref. ACL/MM. 19th September, 1921. Messrs. Rolls Royce Ltd., Nightingale Road, DERBY. X.4359S X.4342S. Dear Sirs, for the attention of Mr. E. {Mr Elliott - Chief Engineer} Fowler Clark. We are despatching to you today the Model 4D dynamo and Model 5S starter which you require for your Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) engine. We would point out that the Model 4D dynamo represents the best which we can do for a machine of this size but does not come up to your specification, but we may say we do not consider it possible to conform to this with a machine of the dimensions in question. In connection with the starter motor, as previously stated in several letters, we do not think that this machine with a gear ratio of only 8 to 1 will start the 6 cylinder engine of which you gave us particulars. We shall, however, await with interest the results of your tests. Yours faithfully, p.p. S SMITH & SONS (LTD. (Sgd) Archibald C. Lock. Manager, Electrical Department. | ||
