Hi,
I have the project to make such a research utilizing the same method I've already utilized with the Il-2, Il-4 and other types: to collect all the available photos, to divide them by resemblance of the version and pattern, then to obtain drawings of the recurrent patterns and their connection with the type, period and factory.
At the end, this work can confirm or make obsolete the one of EP.
His part on the I-16 was deluding, because all 3 patterns of I-16 were based on one photo each, guessing the camo of the other side, and he didn't see that most of them were variations of the same NKAP pattern

The part on I-153s was deluding again, because I didn't found any common pattern in all the photos I have.

Some has already done here,
