Thanks again Ed,
in the second photo album You've linked to there is an interesting picture included, showing the grave of a Bf-110 crew that perished somewhere presumed to be in France.
By using this picture as a reference it turned out that the original inscription on the burtal-cross was somehow faulty.
If You and other laddies here may be interested in what international cooperation is able to manage for the public profit by digging out puzzles of history, just have a look at

Thanks for all the attention and a special one once more to Ed
Norbert
P.S.: The entry at lostaircraft i am refering to is incomplete. So any further additional is mostly welcome to fill the obvious gaps.
