| RHC. {R. H. Coverley - Production Engineer} from Hs {Lord Ernest Hives - Chair} /Gry. {Shadwell Grylls} mis Hs {Lord Ernest Hives - Chair} /Gry. {Shadwell Grylls} 7/KT.22.3.33. PEREGRINEExperimental Bentley car never produced / Aero Engine GEAR RATTLES. We have had considerable success in eliminating rattles with the damper to Hs. {Lord Ernest Hives - Chair} 750. We now want to find out the minimum inertia with which it will work. Will you please make for us a further pair of flywheels to Hs. {Lord Ernest Hives - Chair} 966 as soon as possible so that we can complete our tests. If it would be quicker to make them in S/M or I/C, either would be suitable for a test. Hs {Lord Ernest Hives - Chair} /Gry. {Shadwell Grylls} | ||
