Leslie} I have yet to try a soft ride with this arrgt D P Modified Front Suspension Shock Damper - Phantom III We have received information that by certain enlargements in the passages of the front suspension shock damper a cure for knocks has been effected. We have been given the details of the experimental parts and from them we have produced N.Sch.4946 herewith, incorporating their essential features in a design which it is intended may be tested with a view to standardisation. On the scheme we have indicated exactly of what each of the individual modifications consists. As the cure of knocks is a matter of serious interest it is desired to test this feature on the next car to go to France. Ev.{Ivan Evernden - coachwork} Att:N.Sch.4946 | ||
