| To RHC.{R. H. Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X223. c. to E.{Mr Elliott - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} 8/KT. 9.11.33. BENTLEY EXHAUST MANIFOLD. We have had repeated exhaust manifold failures on the test beds. So far this failure has not reproduced itself on the road, but we think we can with advantage allow more expansion room on these manifolds. Will you please cast one to BV.11 attached, which we should like to fit to the next 10,000 miles test car. We should also like to have 1/2 doz. of these manifolds available for test bed work. Those you have made to the present drawing can be handed over to production. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
