| Bond/R.{Sir Henry Royce} 25th October, 1937. J.S. Inskip, Esq., 10 East 57th Street, NEW YORK CITY. Dear Inskip, We have now got a complete cure for vapour lock, this consists of high pressure petrol pumps in the frame. During the recent hot weather in France, we fitted this scheme to an American's car - Mr. Baker, Chassis 3.BP.163. If you get hold of this car you will see exactly what the set up is. We have sent 3 sets of these high pressure petrol pumps, together with the necessary piping, over to you, and if you feel that the trouble is sufficiently serious to warrant all your cars being dealt with, perhaps you will write us further on the subject. In Europe we only get vapour lock under extreme conditions of altitude and temperature. With regard to over-heating in traffic, we have had this trouble in London ourselves, and have developed an improved fan. With the earlier cars there were one or two cases of radiators being blocked, and you will have received Depot Sheets telling you how to deal with this matter. We also wrote to you on August 17th. Kind regards, Yours sincerely, | ||
