Thanks, Adriano, but to me, it is important to publish these materials in Hungarian language at first (well, it was amazing to see on the old pilots, how proud the become after my aces book released, including the ones, who refused to talk about the war for decades, like Endre Németh).
Thanks, Dénes (it was me, who asked him to comment this topic).
It is true, of course, that there is a significant difference among the authors (i.e. basic quality of the materials), but according to my knowledge and experiences, the Osprey makes significant number of avoidable errors in these books (which is not nice to me).
But we should really forward this part of the discussion to this topic:
