| 2. Rm{William Robotham - Chief Engineer}/Std.11/MH.{M. Huckerby} we would like to receive at your earliest convenience a quotation for this thermostat in the above form - the elimination of the ball valve (and subsequent sweating operation) and the plating should reduce the figure of 6/6 which you have already given us. Your quotation should provide for drilling a .070 dia. hole somewhere in the thermostat flange. Yours faithfully, for ROLLS-ROYCE LTD. | ||
