| +42 To Hs.{Lord Ernest Hives - Chair} from Sg.{Arthur F. Sidgreaves - MD} Copy to Wor.{Arthur Wormald - General Works Manager}E. [underlined] Re Bentley Shock Damper Control. [underlined] Sg{Arthur F. Sidgreaves - MD}7/E26.11.34 [underlined] Would you please let me know the ratio between the standard damping prior to the introduction of the controlled type and the minimum - and separately the maximum - position with the controlled type. What I am wondering is in new[overtyped with XXX] view of my experience with Lp{Mr Lappin}'s car - (see separate memo.) - have we reduced the amount of damping to such an extent as to render the shudders and wobbles more likely to occur if the brakes are used when the control is not in the maximum position?
