Hi,
Here is the photo in question:
Actually, the number on the D.VII fin seen on the extreme left is, I believe, a number 4. This photo was generously supplied from the superb collection of Jasta 43 photos held by Wouter Warmoes. According to Wouter's notes on the well-known line-up photo of D.VIIs, No. 4 was flown by Ltn d R Josef Keller. If the two photos show the same airplane, then this was the aircraft with the horizontally striped red (?) and white nose, white rear fuselage with what SEEMS to be a red (?) raven on a dark rectangle. It is certainly possible that this machine originally came from Jasta 18, and the chordwise stripes on the white tailplane/elevator were part of the unknown Jasta 18 pilot's personal markings. It also seems that the stripes were eventually painted over with white to produce an entirely white tail section, which was eventually seen on most Jasta 43 D.VIIs. This D.VII has been discussed on this forum before.
Be cautioned that this is a LOT of speculation and guessing! In other words, I'm not sure of any of this. I'm sorry that I cannot supply more information.
Osterkamp, thanks for your kind words about the book. Norman Franks and I are grateful for your words of appreciation.
