Chris,
I have check out all images of the captured planes from the site mention above and find another image of black 6/ white 70. Here you are:
As you can see it does not have yellow rudder but camouflage and style of mottle are differ from side to side [larger on port side]. But you are right and other planes from units very possible have yellow rudder [or maybe light blue]
Another image which interest me is this one:
Any idea about the place and unit?
Cheers
