Hello Philippe
I worked and still working on DAT patrols as you know by my info on Chatearoux via Mateusz.
You'll find info in my old (and so on not so good) book HS Avions n°7. There are also good info in B.Belcarz books on polish air forces & and Greg Slizewski "Lost Hopes".
I make you a MP.
Anyway if someone have pic or other new info i am also interested
Matt
