SCHEME 2793. Temporary scheme of friction head by DA.{Bernard Day - Chassis Design} not now required. N. SCHEME 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 contraction crack. R.{Sir Henry Royce} | ||
