HC Deb 29 November 1945 vol 416 c1766W
Mr. Cobb

asked the Assistant Postmaster-General what proportion of telecommunication equipment, including all classes of radio apparatus used for telecommunication purposes, installed and used by the British Post office is the direct outcome of research done by Post office engineers; and what proportion was the outcome of research originating in Great Britain, the British Empire and other countries, respectively.

Mr. Burke

I regret that the required information cannot be obtained, as it is rarely possible in any class of radio or other telecommunications equipment to state what sources of research have contributed to its design or the relative proportions of such contributions.
