The inscription behind the star means 'Avenge for Khristenko'; an unit emblem is painted forward of the star.
There are traces of repainting on the rear fuselage; according to some sources, planes of 566 ShAP have had two white bands on the rear fuselage as unit markings during Vyborg operation in summer 1944, that were painted off at the time of these photos; the slogan was clearly painted after this, while it's unclear if the arrow marking was older; it seems so, because its white outlines appear much less contrasting than those of the star.
The plane can be attributed to Z.18 because of the conformation of the tail wheel fairing and because of the camouflage of the tail with light brown rudder and dark stabilizer. Unfortunately the arm of the technician covers the gun fairings, so we can't be sure. The drawing of the camouflage is based on a similar-looking plane.
