| x7960 To RHC{R. H. Coverley - Production Engineer}: from Hs{Lord Ernest Hives - Chair}/Gry{Shadwell Grylls}: Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}5/KT.24.11.33. 20/25 CLUTCH. We are fitting the vacuum assisted clutch operation Ex.12466 to 20.G.IV. C's car. An improvement we could effect over 19.G.IV. is to lessen the friction of the system by using needle rollers for the fingers as shown on Hs.{Lord Ernest Hives - Chair}1220. This is a very easy modification, all that is required being the rollers and the bore of the fingers increased to .5917". Will you please prepare the necessary parts.
