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

As far as I understand it, the A and B schemes were never meant to relate to odd and even numbers, they simply alternated on the production line A,B, A,B etc. This meant that if there was an odd numbered security break in the serials then the two schemes would switch.



The obsession with A being odd numbered and B being even numbered (or visa versa!) is I suspect an entirely post-war creation by modellers or historians seeing a pattern that wasn't actually there.
