Ju88 A6+HH flown by Major Werner Baumbach - subtype?

[Simon Schatz]

Hello folks,
I'm sure most of you know the Ju88 A6+HH flown by Major Werner Baumbach.
Photographs can be found in different publications or just try a search maschine.
Always the subtype of this Ju88 is given as A-4, but what I don't understand is the position of the FuB L2 antenna. The position is the same as at the D-1. Could be that the plane was a D-1 and not an A-4 and was used for armed reconnaissance?
I aslo don't understand why the plane had a A6 Geschwader code (Aufkl.Gr.120) although Baumbach flew with KG 30. (Geschwader code 4D)
Cheers, Simon
