Olivier,
as you wrote, W.Nr 120067 and the plane with the unpainted tail (my sources says 120097)are the same plane? Is that correct? It's nearly impossible to compare the camouflage because the quality of the pics in the books is not as good as the pics I have from the plane with the unpainted tail. I found a difference.
Compare the wingtips. 120067 clearly shows another camo.
Cheers, Simon
PS: The plane with the unpainted tail is a He 162 A-2 with the MG 151/20.
