Nothing new really. Geust only gives a potted history of the ROA Air Force, the detail is in the book by Joachim Hoffmann -
Die Tragödie der "Russischen Befreiungsarmee" 1944/1945.
That said, the people from Japo published the only known photograph of a ROA St.Andrews cross on a Bf109 in their book
Messerschmitt Bf109G-10/U4 Production & Operational Service in 2004, see the first image below. The second image consists of two pages of the ROA Air Force newspaper
Наши крылья published in April 1945.
There is some more detail on ROA pilots serving with Flugzeugüberführungsgeschwader 1 here

And finally some documents from my own collection
