There is a problem of several factual errors in certain authors publications, originating from lack of research of either original documents or recent publications. This was stressed eg. in recent discussion on the author's Battle of Britain book, which was based on outdated sources, despite the author was awared they cannot be trusted anymore.
In this case, the author provided false information that Pokryshkin may have been responsible for the kill, and that he scored 59 kills during the war. It should have been obvious for the author if he ever checked primary documents, which do not support Pokryshkin memoirs.
Thus said, I am not going into the problem of the author's Russian collaborators, it is neither my interest nor problem. The only point is that the author was and is perceived as the only one.
