| W/P. To VA. from Rm.{William Robotham - Chief Engineer} 1245 Rm.{William Robotham - Chief Engineer}11/MH.{M. Huckerby}4.8.38. With reference to VA.6/ET.1.8.38, if you are getting a reduction in cylinder bore wear from the use of Adcoids, or other definitely measurable advantage, we should like to know the facts, and of course, these should be passed on to Duckhams. If, however, your test results are found to give only the impression that the engine runs better, then we think it would be very dangerous to generalize. Rm.{William Robotham - Chief Engineer} | ||
