As there is no picture from below, is there lozenge or also blue?
Have you ever visited the Model exhibition in Fürstenfeldbruck? May be we know each other as I have shown my biplanes the last years there.
Cheers,
Frank
It is blue on the lower side.
I had a lot of research about this, and I admit that I am still not 100% sure if it is correct.
I found no picture where I could see a Berthold D.VII from below, so I relied on the sources I had (WNW, Osprey).
When building models in this subject there are so many things you can’t be sure of, sometimes it is necessary to just pick a decision you are feeling good with.
I have been in Fürstenfeld every year, even in 2020. I am sure we know each other, and I know your planes very well, your red/white Bristol is still one of my all-time favourites

My club is the PMVA Augsburg and at our exhibition we also had a short conversation about my Me 262 V1 that I displayed there.
See you
