Thank you all for your comments.
Dirk the point is: what is the word following Flugplatz ? Which Flugplatz ?
...
I think it's written Husum. But next, and hence, was a Bristol Blenheim IV recorded at Husum? And when ?
Same question for Evere by the way.
...
Last I have no image depicting Husum and, of course, cannot confirm my thoughts. I do not recognize Evere though.
Very much complicated that story
