30mm exit:

The chute's missing, the round exits right in the middle of that panel line, so it should be there on any blueprint of the plane.. I'll find one if you haven't already.
Wear and tear on a 152C.. I suppose this would be the same sort of wear & tear you'd find on an H model.

More translations of the Czech text:
150 010 Aalborg 1945:[
no idea what this first sentence means, rough translation is: "To this day (come down) machine/engine, (having/fraught) (contain) (three/of the three) [ruské] fighter."]
Ruské's not in the dictionary. "Ruské kolo" is Ferris wheel, kolo being wheel. Ruska and Rusky are "Russian".On the fuselage appear to be the letters CS, in scrubbed whitish blue (factory code CW+CJ?).
RVD yellow/red band was subsequently painted over in one camouflage color around the tail's circumference. >>> hint of transfer out of 301?
Green four is bordered in black. Upper scheme like V3.
WN 150 005, Cottbus '45:This Ta152 (to merge) after, without number code, (u) JG301. Upper surfaces same as Ta152V3.
