Poderia ser, mas parte do material mostrado é americano e não alemão, e todos estão com o mesmo padrão.
Ainda assim o padrão alemão bate com as fotos, inclusive na existencia da linha preta separando as cores.
Pre-war, 1927-1937
Between 1927 and 19 July 1937, German tanks were painted in the Buntfarbenanstrich (colorful paint pattern). The pattern used three colors: RAL Nr. 17 Erdgelb-matt (matte earth yellow), RAL Nr. 18 Braun-matt (matte brown), and RAL Nr. 28 Grün-matt (matte green). The colors were sprayed onto the vehicle in the wavy pattern, with a different pattern for each vehicle. The borders were to be either feathered, or bordered by one to three centimeter wide stripes of RAL Nr. 5 Schwarz-matt (matte black).
