Here is Cobra from 9 iap, renamed to 211 giap in October 27, 1944. This Cobra has several interesting aspects:
- red star also on the tail - according to the VVS standards but very rare on the Cobras,
- reinforced leading edge of the vertical stabilizer,
- and again, reinforced rear fuselage, panted dark green a partially covering left brace of the star:

The detail view on the artwork painted on the different Cobra, probably still in the USA, also with the inscription:

Another Soviet Cobra with the similiar artwork, but without inscription:

Reinforcement of the rear fuselage around radio compartment, unpainted at this Cobra, is the same as this one at P-39D-15-BE, serial no. 44-2911:
