Hi,
I am the author of the book "Die Knullenkopfstaffel". And i am quite happy to get so much positive feedback for my publication - also in this forum.
Regarding to the post of ErwinR:
My book contains a number of excellent photos, several stories and interesting information of Lt. Hoefer. His crew was the first within 1.(F)/123 to get the EK1on May 29th 1940.
Feel free to contact me.
