A DC3 to identify
 

my grandfather went to Berlin in 1945 and I found this picture in the family album showing a DC3;

this A/C seems to be quite worn out,
and I see the "croix de lorraine" - free french insigna on the nose

I suppose the young first man in the foreground is the pilot
(my grandfather is on the right);

any idea to identify the place or the DC3 ?

Cheers
