[Adriano Baumgartner]

Joao, good morning.

Have you been in touch with Sergio Luis dos Santos? He wrote a book about the German airplanes in Brazil and was working on the second or third volumes...but he has been either busy or not frequent here on the Forum.

I can pass you his contacts.

Nice field of research you are digging in here....Keep going.

Abraço,
Adriano
