| X. 7430 BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to BJ. Hs.{Lord Ernest Hives - Chair} DA{Bernard Day - Chassis Design}2/M3. 4. 28. 'SS{S. Smith}' STEERING BOX. Herewith we send N.schs. 2570/74, shewing alter-native proposals for the steering column box. We have shewn the small worm and box on N.sch. 2574 because of the recent experimental report throwing doubt on the utility of the large worm, but as we think R.{Sir Henry Royce} will still require the large worm to be tried we have sent you the alternative scheme on N.sch. 2570. We expect that we shall get some comments from R.{Sir Henry Royce}, and probably it is undesirable to detail until this, DA.{Bernard Day - Chassis Design} | ||
