| X 378 To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}5/JH. 5. 8. 36. Isolated Change Speed Mechanism. We have already tried N.Sch.4806 in which the outer universal is locked solid on B-23-AE, and find no rattles are produced. Before we can standardise this feature for reducing cost, we should like to try it out on other cars. When therefore, any 20/25 or Bentley car next comes into the shop, will you please have this scheme fitted. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
