This is the Trumpeter 01511 kit in 1/35 scale, of the ‘German Kanonen und Flakwagen’.
For the armored train units of Type BP42, the artillery was increased, following Russian and Polish examples, to four guns, which were not, though, mounted two to a car as in the latter types, but one per separately built ten-sided rotating turret, in order to avoid too-great losses from a direct hit.
The two halves of the train, before and behind the locomotive were identical and consisted of one artillery car with one 10cm le.F.H 14/19(p) gun, one command and infantry car and one artillery and anti-aircraft car with one 7.62cm F.K.295/l(r) and one 2cm anti-aircraft quadruple unit.
