My copy arrived yesterday. At first glance, this volume, which covers the Bf 109 G, Avia B.135 and Dewoitine D.520, seems to be even more interesting than the first one, with lots of photos that I haven't previously seen either at all or in this quality. The artwork mostly looks convincing as well. Kudos to the author and publisher!
