Royal Air Force RAF (Strike) Command Crew Embroidered Flying Suit Patch

RAF Strike Command badge (QEII crown) above the words - 'Command Crew'. In good condition. The late Professor Charles Thomas speculated this was a probably for some RAF entry into some inter-allied competition. Luckily this one comes with its issue slip and reference number paper which dates it to June 1973 and it was issued by 14 MU (Maintenance Unit) - the logistics set up at RAF Carlisle. Any information welcome. Comm ViCr
