Ernst,
That seems logical. The fuselage band has also been over painted. Looks as though when it came back from Billijiord in Finnmark in autumn 42 (operating on the Eastern Front the yellow markings were required). Back on the West Coast the yellow markings were then painted over.
The main plate is interesting. All the normal information. Manufacturer at Rostock, Type He115, W.Nr 2398. Abnahmedatum ? 39. Trying to work out but it looks like 9.39? The tail strut fairing had a part plate dated 9.39 as well by the looks of it. No stamp showing B upgraded to C.
