Good morning...
I'm looking to see if anyone happens to have a copy of Der Frontflieger. Bernard & Graefe, Berlin 1937. by Elard Baron von Löwenstern
With the outbreak of the First World War, he was transferred as an observer to Feldflieger-Abteilung 15, which was stationed in Königsberg which was active on the Eastern Front in the early stages of the war.
