Hanbury - Head Complaints} b. to WDX. c. to Hy.{Tom Haldenby - Plant Engineer} d.{John DeLooze - Company Secretary} to Hs.{Lord Ernest Hives - Chair} CHASSIS COST. ADDITION OF THERMOSTAT TO WATER SYSTEM. The additional cost on the Chassis due to the addition of the Thermostat Control, is £2. 0. 0 (without profit). The introduction of the Thermostat has meant a new design of Water Connections, and also the elimination of the Water Temperature Meter, Blanking Plates, etc. This change in design, I understand, is to be introduced at the 1501st. Chassis. Based on the list got out by Hy{Tom Haldenby - Plant Engineer}, the value of the Material scrapped by introducing this change in design at the 1501st Chassis, is £82. 3. 9 (without profit).
