Karl und Wolfgang Roos(Ehrenpokal)

[cbe2009]

Hello!
I have a problem with Wolfgang Roos. He was a Fw. when he died Juli 25. 1944.
He was decorated with EK I und II, the golden frontflugspange and the Ehrenpokal at the time of his death (Fliegertod).
1) Does anyone know the circumstances about his death, unit, markings etc.?
2) Was he the one, who was part of Hansgeorg Bätcher´s crew in June 42"

In the book on EP recievers he is listed as a gunner, but in Brüttings book on Kampffliegerasse he is pictured with the text as being a mechanic (IF it is the same man??)

I got his brother covered - he was in KG 2 and died the second of Juli 1943.

The reason for all these questions is, that I would like to build models of their planes.
Thanks in advance
Christian Berring
