I want to thank you for the information provided on your website regarding the cooperation of Germany and the Soviet Union after WWI.
I am German by birth (living in Belize). After my mother died I got her diaries. She reports on her youth in Russia. My grandfather was part a a team of Germans who worked in Woronesch, re-establishing German military aviation in the early 30s.
I am researching the historic details that back up my mother's diary. Your site was of tremendous help.
I am in the process of translating said diary into English and plan to publish it online. I plan to link to you site as reference.
