Me 210/410 by P.Petrick&W.Stockler reliability question

[Peter Kassak]

Hi all,

as you may have seen in my last postings, I became interested in ZG 76 while using Me 410s..so I have been adviced to get a new book Me 210/410 book by Peter Petrick and Werner Stockler.
But what a surprise came when I checked the WNr. lists with my already found and databased losses of ZG 76 planes. Regarding Slovakia, there is VERY FEW that are dated CORRECTLY. Also the colour photo of plane crashed in Hungary as given also WNr. is dated WRONG. I completely lost believe in that list...
Can anyone confirm that there was typo error or some other mystakes during the preparation of the book? I just do not want to believe that well know authors can make such a mystake...
