The above decrease in cost should be added to the saving shown under Standardisation Sheet No.X.312. dated 8.6.37. also the estimated cost of new tools shown under sheet X.312. should now read £12.10.0d. instead of £16.0.0d. Deletion of washers G.84938 reduces tool cost of flexible engine coupling (Std. Sheet X.312) from £16.0.0d. to £12.10.0d. It has already been decided that flexible engine coupling shall be standardised at 1st. chassis in "D" series, and deletion of above washers will increase the saving from 1/2d. to 1/6d. RHC.{R. H.
