| To Hr. (W/S). from EFC. " By.{R.W. Bailey - Chief Engineer} By/C. " Wd.{Mr Wood/Mr Whitehead} D/BP. " CY. Ne. " EP.{G. Eric Platford - Chief Quality Engineer} Hm.{Capt. W. Hallam - Head Repairs} X8800 EFC4/T23.4.26. X8800 X8783 Will you kindly note the following extract from a letter which I have received from Mr. G.R.N.Minchin (of Messrs. Peto & Radford). This may throw some light on recent complaints of the burning out of side lamps. "With regard to your question about how is my car behaving. It is behaving extraordinarily well. I ought to have told you that I was wrong in putting down the question of the side lamps burning out as being due to the high voltage. After I had written to you I happened to mention the fact to Mr. Oliver Lucas and he said that a consignment of bulbs had got through from the lamp manufacturers about that time with the wrong filament, and he sent me some others in their place and confirms that mine were among the faulty ones and since I put the new ones on I have done about 5,000 miles without any trouble at all. As there was trouble with these side lamps on other makes of cars with different electrical system, the trouble evidently was lamp trouble and not due to our battery or your dynamo or anything to do with the Rolls Royce system. I ought to have told you about this before." EFC. | ||
