An Anlasswagen connected to Me 210A-1 coded 2H+DA, of Versuchsstaffel 210 (based in the Netherlands), spring 1942. This appears to be a rather different model. The hooded engine and generator are absent. The color of the cart appears to be black, it is even darker than the fuselage iron cross. Note the markings 'Werft' and the number 3.
