Most of the pictures I’ve seen of 1946 Aircrew Scheme personnel are where they are wearing Battle Dress/War Service Dress. Whilst the picture I posted above shows some in No 1 Dress, have you got others where they are not in Battle Dress? That is the only difference I can think of and your 1st picture shows an individual in No 1s too. I then wonder if it is one of the vagaries of the 1947-pattern No 1s?
