(crossed out) Seder (handwritten signature) LOCKING OF 5.B.A. LOCATION SCREW IN ROCKER SHAFT, WRAITH, BENTLEY & 30 HP. /1360. 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/Ald.{F.
