Dear Sirs, 'For the attention of Mr. Robotham.' Re: Automatic Jet Control. With reference to the above we understand from Mr. Skinner of the S.U. Company, that he is of the opinion that as two Carburetters are employed it would be advisable to use a more powerful type unit to control the two jets. As you are aware, the model submitted to you has a 40m/m.{Mr Moon / Mr Moore} metallic bellows and in order to obtain the necessary extra power, we suggest our next size, namely 60m/m.{Mr Moon / Mr Moore} diameter bellows. We are, therefore, enclosing you blue print No.EX.X.7244 which gives the overall dimensions. If it is possible to accommodate this unit in the water jacket of the engine, we shall be very pleased to send you a model, either to your goodselves or to Messrs. The S.U. Company, for fitting. We also enclose you our Blue Print No.EX.SK.7257 which shows the method of clamping the device in position. Awaiting your reply and assuring you of our best attention at all times. Yours faithfully, p.p. S. SMITH & SONS (MOTOR ACCESSORIES) LIMITED. [Signature] THERMOSTATIC CONTROL DEPARTMENT. | ||
