| W/K. To Rm {William Robotham - Chief Engineer} /GWH. {George W. Hancock - Head Chateauroux} from Rm {William Robotham - Chief Engineer} /Les. Rm {William Robotham - Chief Engineer} /Les.2/AP.5.2.37. SHOCK DAMPER BEARINGS. Re your note of the 3rd inst. 38-EX. had only done 2050 miles last Monday. I presume that you therefore mean 34-EX., which has probably not had its dampers changed for two years and is quite liable not to have been fitted with 100% bearings. We are now trying to develop a damper which will be quiet even with slack bearings. Rm {William Robotham - Chief Engineer} /Les. | ||
