Who knows Oberfeldwebel Kurt Raffani
 

Hi all!
I'm looking for information about a member of the german air force named Kurt Raffani. A friend who is a militaria collector has a document (no fake!) that he was awarded with the Luftwaffe Ehrenpokal (Honor Goblet), dated 1-Nov-1943. At this document he was ranked Oberfeldwebel and Schlachtflieger.
Any help appreciated!
