| x209 To RHC. {R. H. Coverley - Production Engineer} Hs {Lord Ernest Hives - Chair} /Smth.18/KW.6.6.34. Supercharged Bentley. In view of the somewhat uncertain performance of the Graham Supercharger we wish to have a spare set of worm gears of higher ratio, in case we cannot obtain a sufficiently high boost with the existing arrangement. Will you therefore arrange, if possible, for a worm drive giving a step up of 4.34/1 to be made in addition to that already instructed. We shall thus have available two overall step ups, namely 5.76/1 and 6.50/1. Hs {Lord Ernest Hives - Chair} /F.Ll.Smith. | ||
