With reference to memo Rm {William Robotham - Chief Engineer} /Swdl. {Len H. Swindell} 5/JH.31.12.37. asking for a positive lock for the above 5.BA. screws, we have now received a complaint from RHC {R. H. Coverley - Production Engineer} /Wld. regarding the difficulty of producing a tab washer as small as 5.BA. We therefore suggest increasing the screw diameter to 3.BA. and fitting a KB.2952 Tab washer; tools for this latter size having already been produced. Rm {William Robotham - Chief Engineer} /Swdl. {Len H. Swindell} is in agreement with the above. Will you kindly advise us when this change is made. aed (handwritten initials) BY {R.W.
