Steffen, some notes about painting scheme of your Chaika.
Some I-153 had sealing tape on the tail fairing, like this one

It looks like your I-153 had it as well:

Unfortunately I don't know what color it should be

. And I'm pretty sure that tail should be silver, not white. I guess that this Chaika was repainted from standard prewar silver, and tail was left in its original color. Also it has antenna mast on the upper wing.
