As I said, 2 GvAP DD operated IL-4s in Sept, 1944:
A nice drawing of IL-4 No.21, perhaps the very same plane:

Not sure (and honestly: I don't really care) about any of their earlier B-25s.
26 AP DD(?) Mitchell in photo: I think it is wrong too, since that unit did not operate in the Hungarian area, it was (almost for sure) one of the lost 5 GvAD DD (14 & 22 GvAP DD, 337 AP DD) Mitchells, carrying supplies to the Yugoslav partisans flying across the Carpathians, Rumania, Hungary in the spring and summer of 1944. Many were lost due to German NJG attacks, flak and other mechanical troubles. Other candidate would be a 362 AP DD Mitchell (eg. B-25D, S/N: 43-3827) which also participated in raids against Hungarian cities, eg. Budapest, Debrecen in Sept, 1944. A 2nd GvAP DD Mitchell (if they had any left beside their IL-4s, - that I strongly doubt!!!!!!) would have flown back home towards Belarus, where all of the 2nd GvAP DD IL-4s turned after attacking Budapest. They wouldn't have been lost in Rumania or in -E, -SE direction from Hungary, an almost opposite direction!
