Hello Volker!
Quite wonderful pictures! I do have tried to identify the flying boat, but got no joy...
Here´s a link to the Dorniers flying boats

Could it have been a foreign flying boat captured by the Luftwaffe; or a civilian model also used for VIP or General purpose flights?
Did your father fly on operations? I remember a technician from Siemens and Telefunken that came to Brazil after the war. He told me he was with Hptm Lent when the first FuG 212 were installed. He also mentioned a flight he did with the Me 410 on night-fighter duties being a technician! On that mission they shot down a 4-engined bomber from the RAF. He died some years ago, but I enjoyed talk with him.
It is good to see that you do have interest on the achievements of your family. You came to the correct place. There are a lot of wonderful people here as well as a dozen of very Expert Writters and Historians ( with huges W and H ).
Wish you all the best
