| To Rm{William Robotham - Chief Engineer}/STD. from G/Rb.{R. Bowen} G/Rb.{R. Bowen}6/K/73/R.251137. 1260 hW Rm{William Robotham - Chief Engineer}/STD Wraith Chassis. Radiator Steam Valve - SEC.5250. Rm{William Robotham - Chief Engineer}/Std.6/JH.23.11.37. We have investigated the cost of the Steam Valve combined with the escape connection to RM.{William Robotham - Chief Engineer}417 and find this modification shows an increase in factory cost of approximately 1/1d. per chassis.
