Jasta 43 Fokker D.VIIs

[2996 Victor]

Hi,
I'm planning a small vignette displaying four Fokker D.VIIs of Jasta 43 and my intended subjects are the mounts of the following pilots:

1. Oltn Adolf Gutknecht
2. Ltn Josef Raesch
3. Ltn d R Simons
4. Ltn Freidrich "Freidl" Jakobs

Raesch's aeroplane is well known as having a red nose and forward fuselage, a white tail unit, and a black trident/pitchfork marking.
Simons' (does anyone know Simons' first name?) aeroplane had, according to Wingnut Wings, a red nose, red/white horizontally striped fuselage, and white tail unit.
All good so far, but here's where my question lies. Most literature (and profile images) give the aeroplanes of Gutknecht and Jakobs as being black with white details and tail units.
However, Dan-San had other ideas about Jakobs' mount, as here:

This makes sense as it is known Jasta 43's first Fokkers came from Jasta 18, and I will go with red on my model when it gets built.
I have lately been wondering about Gutknecht's mount as well. There is this well-known photograph of the Oberleutnant and his ground crew standing in front of his D.VII:

Raesch's machine is in the background and gives, I believe, a useful guide for comparing the red and black tones and shows how similar they appear on film.
Studying Gutknecht's machine, the tone of forward fuselage and the broad band between the two white bands appears to be slightly lighter in tone than the rear fuselage band with the balkenkreuz, very much on a par with the forward fuselage of Raesch's. Thus, I think that the forward fuselage and the broad band between the two white bands are actually red, while the rear fuselage band with the balkenkreuz is black. The wing crosses can be seen to have been altered while there is no sign of that on the fuselage, which further suggests that the rear fuselage was re-painted entirely when the new style crosses were introduced.
I would be most grateful to hear other's thoughts on this.
Many thanks and kind regards,
Mark
