| 1245. To Bentley Motors Ltd. Derby............... Rm.{William Robotham - Chief Engineer} Levallois Sr6/ET.17.8.38. Dear Rm.{William Robotham - Chief Engineer}, I have just come back from a ten day cruise around the British Isles. There was nothing much to write home about, but the cruise was excellent. It is most unfortunate about the Streamlined having crashed. This upsets all our plans. However, we will get the car over to you in September. Could you ask one of your lads whether they can give me any explanation of the reason of a repeated low speed wobble on a 4 1/4 Bentley belonging to one of our very good customers, Mr. Pierre Louis-Dreyfus. He is a most meticulous man and, in spite of having all the latest modifications, including the Hancock modification, the wobble continues. We got over this trouble by fitting INDIA tyres instead of Michelins, but this does not seem to me to be the right way of solving the problem, as the customer prefers Michelin tyres, and moreover there are numerous Bentleys running about France fitted with Michelin tyres, including all the Bentleys belonging to the Michelin family, and no low speed wobbles have been worrying them. It may just be something silly and you have had experience which may help us to put the matter right mechanically. The tyres we have removed had covered about 5000 Kms. Thanking you in advance and with kindest regards to Mrs. Rm.{William Robotham - Chief Engineer} Yours sincerely, Sr. p.p. E.T. | ||
