| 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. PEREGRINE 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} | ||
