It is indeed Banfield; well done. Interestingly, his German-language Wikipedia page gives him the "Freiherr" (roughly "Baron" in English) title only from 1917 to 1919, perhaps on the theory that when Austria-Hungary dissolved its titles vanished with it.
He was born in a city that was then in Croatia but is now in Montenegro, making him, according to Wikipedia, the only ace born in that country (i.e. Montenegro). Not that this matters at all.
