The rudder markings book is very good in terms of accuracy there are a couple of miscaptioned shots, and even some of the unknown ones in the back section can now be identified.
Clint,
contact Jim Perry for a pdf copy of his " Errata et Addenda - Ries/Obermaier, Bilanz am Seitenleitwerk " which comprises approx 30 pages of detailed caption text for this book..produced by luminairies such as Caldwell, Beaman, Morrison, Kitchens et al.. I think he sends it out free of charge..
