We have solved the mystery of the Bullimore ration coupon on the last post and where it came from (an anonymous donor). Looking through the Bullimore folder, we came across this other document about RAF restrictions on movement in 1943. ‘Within the bounds of this Unit’ meant those towns which an airman based at RAF Lichfield and carrying this pass was allowed to visit. This brought a wry smile given the current situation of lock-down in the UK and other countries.
According to the website History of RAF Lichfield, 51 MU moved into RAF Lichfield on 1st August 1940. Their job was to receive aircraft from the various manufacturers and carry out the modifications required before delivery to the individual squadrons. After the war, they took on a more destructive role and broke up large numbers of suddenly obsolescent aircraft.
