| Description | Harrison acknowledges Davidson & Co's letter quoting £6 for installing the "Sirocco" fan and motor, as specified by Mr [Charles Vernon] Boys; and £3.5 for a galvanised steel discharge mouthpiece. Harrison accepts Davidson & Co's estimate. If it make no difference to the cost, Harrison wishes that the door in the discharge mouthpiece should be hinged on the lower edge and balanced with a counter weight. Harrison presumes that the estimate includes the cost of fitting the switch. |
