| Hs.{Lord Ernest Hives - Chair} DA.{Bernard Day - Chassis Design} E.{Mr Elliott - Chief Engineer} BY.{R.W. Bailey - Chief Engineer} from R.{Sir Henry Royce} X7520 R2/M17.1.29. 'SS{S. Smith}' N.sch.2793. Temporary scheme of friction head by DA.{Bernard Day - Chassis Design} not now required. N.sch.2794. Strengthening of front shock damper scheme - agreed good and necessary. From the figures given it would seem that failures were due to stress change, or concentration, or concentration crack. R.{Sir Henry Royce} | ||
