As a Swift enthusiast, I'm sure that you will be aware of this book, but in case not;
"Swift Justice" by Nigel Walpole, puublished by Pen and Sword ISBN 1 84415 070 4
I have a feeling that there may be other books on the Swift. Also ISTR that Dave Morgan (ex Vickers Supermarine test pilot) wrote a number of articles in Aeroplane Monthly in defence of the Swift, which he strongly felt had been wrongly maligned.
