Replying to your memo. Cx.{Major Len W. Cox - Advertising Manager}16/KW.3.5.39. this is the first time any complaint of ineffective undershielding on Wraith has come to our notice, none having been received from service. It would be of great assistance to us in carrying out our investigations if you could intimate to us whereabouts you think the mud enters. There is a wider space unshielded beneath the fan, than on 25/30, but we do not wish to add a shield at this point before we are certain that this is the source of your trouble.
