[G.R.Morrison]

I do not have any He 115s with a Stammkennzeichen beginning "VF+" but our data is nowhere near complete.

As you likely know, if there are no casualties in the course of an incident, names aren't recorded in a loss report, but a unit diary may list those rescued.

Although it's common that "the boss" might use "A", but this is by no means universal, and the determining factor is more-often "which airframe is operational." The previous Staffelkapitän was Hptm. Eberhard Peukert, who was injured in a crash after striking the sea while evading fighters in "8L+BH" (WNr.3246) on 25.April 1942. The succeeding Staffelkapitän of the 1./KüFlGr.906 was Major Horst Kayser, who later was MIA in Dec. 1942 while leading the III/KG 26.

The Do 24T WNr. 0047 CM+IM was lost 10.Dec. 1943 east of Froeya Island (with -likely - a different crew?), but on the 15.Sept. 1942? Sorry.
Peter de Jong's excellent Dornier Do 24 Units mentions the incidents, and includes a photo of the tailless 'boat,' but no names.

Good luck in your hunt, GRM
