Hello,
Chris Goss is talking of that book, writen by Nick Beale and D'Amico:

Perhaps if you put your question openly, some of the members may be able to help you. For example, a friend of mine do quite a lot about the 1st Brazilian Fighter Group in Italy. There are some 256 and 600 Squadrons experts here too, etc...so, if you try to narrow what you are looking for, perhaps a 100% hit will be obtained.
