Hi,
the page is under construction since the very beginning of the site, that means abandoned (at least temporarily) because the liveries available for this beautiful plane are disappointingly repetitive. I have also a model on work, stopped in advanced state (already painted). Fairly good kit, I would say.
There is one plane positively identified as camouflaged. At present time , I don't know the unit.
Here are some:

For the parts where camouflage is not visible, I would take into account this sketch from NKAP standards (From Vaklamov and Orlov's booklet)
There is an issue of Aviakollectsia on this plane, a nice monograph. I can't find it now, but it should be available online.
Regards
Massimo
