HC Deb 05 July 1933 vol 280 c323
22. Mr. MANDER

asked the Financial Secretary to the War Office the position with regard to the adoption of the new searchlight made use of for sky-writing for the equipment of the air defences of this country, and the reason for the delay?

The FINANCIAL SECRETARY to the WAR OFFICE (Mr. Duff Cooper)

As a result of the investigations made, the probable value of this searchlight for air defence was not considered to warrant the expenditure demanded.
