Hello!
Lookin' good - and I'm glad to see it! Not only do I love to see something Polish on the 'net - Zumbach was a very special man who embarked on funny careers after the war. The British almost kicked him out when it turned out he actually is a Swiss citizen (but born and raised in Poland). So he went on to be a smuggler and smuggled mainly watches from Switzerland. He also fought as a flying mercenary in Africa in two separate wars. He also owned a Disco club in Paris.
He wrote a book about his life before, during and after WWII - I don't know if it's been translated to English, but it's a very good read.
They say that Donald on that Spitfire got there because of the way Zumbach tended to talk :-)
Thanks for sharing and have a nice day
