Searching for a record of fighter pilot Fritz Güntermann

Hello everybody here,

My name is Barry, and I live in Belgium.

I have in my possesion 5 pictures of a german ,I think, fighter pilot.

This is the story;

In WW 2, my grandmother lived near Wevelghem (Wevelgem) Flugplatz.
Early 1941, she met this man, Fritz Güntermann.
He was a Luftwaffe member( 2 wings like emblems on his uniform) .

My grandmother got 5 pictures from him.

One picture depicts a Bf109-E I guess.

I know he came from Poland, and left Wevelgem in February 1941 to Cherbourg.

Does anyone know wher I could find more info ,about his rank, his military career?

Best regards,Barry
