Uh oh....
That sounds not good. More confusion then before.

Thank you very much for your replies. Are there any informations about the type of test's are made with the planes?
E V25 1930 D-IVKC NB+NG 09.39
That is helpful, because my guess was going in that direction for this plane. To bad the Stammkennzeichen is not full visible...

Can we be sure that the airfames did exist twice with the same V-number? Can it be, that the heavy modified airframes just become new WNr.'s?
Are informations known about the fates of the "first" airframes?
And btw, there is a special publication on the book market about the V-planes. I don't got it, because I'm not sure to get any new informations from it.

"Dieses Buch wird einiges, was Sie glauben von der Bf 109 zu wissen, auf den Kopf stellen."
Also the twice V number fact/theory?
Thank you all!
