I found this Website
http://www.jg5.szm.com/Verlusten/pohl_ottokar.htm
but I'm not sure this is correct. There is no mention of Fw Pohl in theJG-5 histories I have.
Also, there is this excerpt from the Web,originally from the Montreal Gazette July 1968:
"Ottokar Pohl, president of the Czechoslovakian National Bank, was in West Germany recently talking with several commercial bankers."
Because of the unusual name, I think this could be the same person.
