HC Deb 29 February 1940 vol 357 cc2235-6
37. Major Sir Jocelyn Lucas

asked the Home Secretary whether his attention has been called to the inexpensive black-out shutter used by the Portsmouth air-raid precautions authorities which combines a complete black-out with ample ventilation; and whether he will have the plans of this and any other design having the same advantages made available not only for other air-raid precautions authorities but for private householders as well?

Sir J. Anderson

I have asked for full details of this device to be sent to my Department, and when they have been examined, I will write to my hon. and gallant Friend.
