| x209 To Hs.{Lord Ernest Hives - Chair} from Sg.{Arthur F. Sidgreaves - MD} Copy to Wor.{Arthur Wormald - General Works Manager}E. [text struck through] re Bentley Supercharger. Thanks for Hs.{Lord Ernest Hives - Chair}15/MJ.8.5.35½. I appreciate the position. What I was really wanting to try the car for was to see what benefit was obtained by the fitting of the supercharger and what the disadvantages were - if any - from the point of view of increased roughness or noise, bearing in mind that on the Graham Paige no disadvantages appeared to exist. Perhaps the best way will be to wait until I next come up to Derby to try the car. Re the larger bore unit I note that you hope to have this on the road next week and perhaps I can try this at the same time. Sg.{Arthur F. Sidgreaves - MD} | ||
