Telephones VICTORIA 6242 (7 LINES) Messrs.Rolls-Royce Ltd., Experimental Department, DERBY. Attention of Mr.R.M.Child. YOUR REF. Rm{William Robotham - Chief Engineer}/RC.{R. Childs}15/JH. OUR REF. BR/RS.{Sir Henry Royce's Secretary} 12th April 1939. SUBJECT Dear Sirs, With reference to your letter of April 5th. referring to our latest type vacuumatic distributor, it should be possible to fit the vacuumatic type of distributor to a Wraith engine, and we accordingly enclose copy of our drawing 9-A-9863 showing the general dimensions of such a distributor. This could be fitted with a flange and the shaft end machined to be interchangeable with your existing distributor. You will note that the cam is of the 8 lobe type used with a single circuit breaker arm, the "build up" is therefore less than that on the 3 lobe type of cam. If you think that this point will not affect your performance at high speed we will make up a sample unit for you. This actual distributor is the one we are using on the Lagonda. Yours faithfully, B.Rushton. Technical Director. | ||
