| 5250. To Wor.{Arthur Wormald - General Works Manager} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to G/Rb.{R. Bowen} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/MJ.3.12.31. RADIATOR DROPPED 4" IN FRAME. 20/25 HP. STANDARDISATION SHEET X.5250. With reference to the above standardisation sheet. At the same time as the altered radiators were introduced, thermostatically operated shutters also came into production, although these were originally tested on an old type radiator. We have also incorporated the Hexagon copper tubes at the same juncture. As both these items will effect the cost, the heading of the Standardisation Sheet should therefore read - "Radiator Dropped 4" in the Frame, Thermostatically Operated Shutters, & Hexagon Copper Tubes."
