The jacket in Gary's book is a SAT in my opinion. It has all the same details as the one "The Art of the Flight Jacket". When Gary's jacket was refurbished the original label was retained and re-applied to the lining. I very much doubt if an air depot retained labels (presumably from jackets that were beyond repair) to put in other ones! In the mean time I will carry on looking for pictures of labelled SAT A2s.
