| 1269. STD To [REDACTED] & Rm.{William Robotham - Chief Engineer} From RHC.{R. H. Coverley - Production Engineer} RHC.{R. H. Coverley - Production Engineer}1/MC.17.11.38. Water Pm / S809 WRAITH WATER PUMP With reference to EY.6/G.16.11.38., we would state that Water Pumps are now actually assembled for chassis up to 150 in "B" series, whilst material for the remaining 50 chassis of "B" series is in a finished condition. When this question was previously raised it was pointed out in our memo' RHC.{R. H. Coverley - Production Engineer}1/MD.15.10.38., that considerable dislocation would arise if a new design were introduced during "B" series, whilst any change at the present juncture would have infinitely more serious results. Since the new pump cannot be introduced before "C" series without retarding production, it, therefore appears that retrospective action will be necessary to overcome these complaints. RHC.{R. H.
