| x7360 To By. {R.W. Bailey - Chief Engineer} c. to H1. c. to RHC. {R. H. Coverley - Production Engineer} Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 11/KW.1.11.34. We are somewhat concerned at the wear which took place on 28-EX rear drum. We have been talking to Mr. Longley of Ferodos and in his experience the wear of these cast-iron drums is exceedingly sensitive to their composition. We are sending him one of our photomicrographs and his opinion on it would be interesting. In the meantime I think it would be as well to let Messrs. Lake & Elliot have a sample of a drum and get their opinion on it. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} | ||
