Hi Wim,
Thanks for the thorough explanation. So now we have G9+DX repainted as 3C+BA at Eggebeck and G9+BA at Schleswig (it is two different airfields) also with repainted rudders. And BTW it is Bf 110 not Me 110

.
And if your explanation is correct, then the Wiki picture should read:
at an airfield in Schleswig-Holstein with the code 3C+BA. And this was my entire purpose of getting involved in this discussion.
