Focke Wulf 187 by Hermann/Petrick
 

Hi all,
according to the book shop http://buch-arsenal.de for the book "Focke Wulf Fw 187, Der vergessene Hochleistungsjäger" there is now a completely revised edition of this book available. Does anybody know the difference between the first edition from 2001 and the now published third edition?
Both books have the same number of pages.
Thanks in advance,
Robert
