Gentlemen:
The Halberstadt in photo in the #33 posting is either a Halb.D.II or D.III. It has the extended trailing edge on the aileron.
Photo #35 of
Kurt Wolff is standing in front of a Halb.D.V. The upper nose cowl is the identifing clue. The extended chord aileron on the Halberstadt in the background is either a D.II or a D.III. Too bad there is not a flight line photo.
Blue skies,
Dan-San
