This is an apolitical forum for discussions on the Axis nations and related topics hosted by the Axis History Factbook in cooperation with Christian Ankerstjerne’s Panzerworld and Christoph Awender's WW2 day by day.
Founded in 1999.
My copy arrived yesterday. At first glance, this 2nd volume of 'Bulgarian Fighter Colours 1919-1948', 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!
