The Control of Mills (Flour and Provender) (No. 1) Order, 1939, prohibits millers from milling or delivering.any cereal or manufacturing any cereal product except under licence and provides that any specified conditions may be attached to such licence including conditions as to the quantity and type of product which may be manufactured. On 3rd September, 1939, the Board of Trade issued a General Licence (as amended by Order dated 9th December, 1939) authorising all flour millers to continue to manufacture, but prohibiting, except under special authority, the production of any flour other than straight-run flour as defined in the Flour (Prices) (No. 1) Order. The Board have in a few cases issued special licences to individual millers for the production of flour other than straight-run flour. No special licence is required to produce wholemeal flour which is covered by the definition of straight-run flour.
