I picked up these two patches today from the Newark Air Museum Aeroboot Sale, i found the second patch very intersting and was informed by the seller that this patch was issued to all the aircrews who took part in the show... i would like to know more about it... if any of you guys could shed more light on this Alconbury patch it would be very much appreciated with all my thanks in advance.
