HC Deb 26 June 1952 vol 502 cc198-9W
52. Mr. Powell

asked the President of the Board of Trade the value of mathematical instruments imported into the United Kingdom during the latest convenient period, compared with corresponding significant earlier periods since 1945.

Mr. P. Thorneycroft

I regret that this information is not available as these instruments have not been separately distinguished in the trade returns since 1949.
