Was it a problem if a MU repair changed aircraft from A scheme to B scheme etc

Great thanks - As an example it seems Hurricane L1592 was damaged in action on 15th August 1940 flown by P/O Looker of 615 Sqn. It was produced in a B Scheme at Brooklands in the first batch. So I understand Hurricanes built at Brooklands with ‘even’ serials numbers in this batch all had ‘B’ schemes

And yet after repair in August - September 1940, it acquired an A scheme but just to confuse, its starboard wing was in an B scheme (which its believed came from L1562). Although the starboard wing was repainted in service, it retains the 'wrong' scheme to this day in the Science Museum, London.
