Gentlemen,

for the moment many thanks for the outstanding response and helpful hints.

It will take time to find the answers. Different time-schemes, different perception of the location (defending fighters vs. attacking bombers with their fighters) all this has to be taken into account to find Karls history.

I would be glad to find some answers in order to summ it up in a small story of his short life which I would like to present to the Knichels and interested people on the occasion of Karls 100th birthday in October 2019.

Regards

JFK
