that looks like 55thHey guys ... the number is what matters! We maybe have a new brigade confirmed.
that looks like 55th
i'm inclined to believe scramble has additional sources on this.
Left : xx664 .... 6665x : Right
Left : xx664 .... 6665x : Right
Me again ... In fact I'm still not 100% sure ... if you look closely, then the penultimate digit looks more like a 5 than a 6, which would suggest 66x54 instead of 66x64 and that would make it the 54th AB, which would be another surprise.

Is 66654 not a strange number though? Would appear to indicate a brigade with at least 64 aircraft. At least all the ones on CMA are XX[0-2]X[0-9].
