| HS{Lord Ernest Hives - Chair}/RM.{William Robotham - Chief Engineer} FROM HDY.{William Hardy} C. to S.G., WOR{Arthur Wormald - General Works Manager}, E, DA{Bernard Day - Chassis Design}, BY.{R.W. Bailey - Chief Engineer} ORIGINAL HDY{William Hardy}2/M27.3.33. V225 DAMPERS - RECESSION OF SYLPHON. R.{Sir Henry Royce} has instructed that the non-return valve with restriction suggested some weeks ago should be given a trial. There will of course be delay in the reduction of damping. It is thought that this will be less serious than delay in the increase of damping, and in any case experience on the road is to determine how serious the objections are. HDY.{William Hardy} | ||
