Thank you for the links; it is incredibly hard to find photos online of the late series for some reason.
Also, then, I am wondering if the colors for the Black Sea Fleet aircraft are correct?
As in, the kits with Schipov's markings usually call out the AMT-11/12 grey scheme, but it's hard
for me to tell from photos whether that could actually be the green and black colors instead.
Reference these photos, this first one is usually shown in the two greys:
Whereas this is Schipov's a/c (if I'm not mistaken?) which the kits now also show as two-tone grey, but looks too dark?:
But this one (one of the ones you mention with the interesting slogans, Massimo) is said to be green and black:
Very confusing, going by black and white photos.
