Hi Steve,
thank you for the message and the kind words on this series on JG 2. Sorry for my late answer but I was "over-worked" and had to lay down a little bit the history-hobby.
This series will be my last chronicle. Up to other ones to publish the missing chronicles of "forgotten" units like JG 2. But their task will be hard if they haven't met the veterans. As far as I know, from JG 2, they must not be over ten since Paul Gassmann passed away a few weeks ago.
Yes, face to the amount of new stuff (mainly photos and accounts), I had to split the volume 1 of the French and English editions in two for the German one.
Here you can find a review for the last volume in French (1943):

Best regards and all the very best for 2016.
