I may have been a little hard on earlier authors in text point 1 when I wrote: “Karl Born stated very clearly that these were the first two Do 24s to see Luftwaffe service with the Seenotdienst and Born never stated that these were the first and second Do 24s delivered during the German occupation.”
The clear statement in Born’s book on the matter of the first two Do 24 assigned to the Seenotdienst actually appeared on one of the photo pages, p.158 “Im Sommer 1940 kamen die ersten dreimotorigen Größflugboote Typ Dornier DO 24 in den deutschen Seenotdienst.” [In the summer of 1940, the first three-engine large flying boats, the Dornier DO 24, entered the German ASR service].
However, in the text on p.140 his statement was not quite so unambiguous: “Es war etwa Mitte Sommer 1940. Wir hatten gerade in Norderney die ersten beiden DO 24 aus Holland bekommen, die besagten weißgestrichen Erstlinge D-AEAV und D-APDA.” [It was around the middle of summer 1940. We had just received the first two DO 24s from Holland in Norderney, the white-painted first models D-AEAV and D-APDA.]

The whole of the paragraph in which this sentence appears is about the Do 24 in service with the Seenotdienst. However, if you put that context to one side, missed seeing the p.158 photo caption statement, and did not check that neither registration specified was assigned to the first Do 24 K-2 delivered to the Germans, you might have thought that in this sentence on p.140 Born was actually referring to the first two Do 24s delivered out of Holland to the Germans.
However, as the primary sources establish, this was not the actual case.

Enough now.
