Hi Keith. There is an outline of 2ACG ops. HERE starting p.40, lots of very nice photos.
You have no doubt seen Study 85 victory list for the Group, total 7.99 in the air ?
I've got a list of the Mustangs on the big mission of 15 March with plane numbers and unofficial claims recorded by a pilot (mostly ground but 3 air) if you want to see.
