Help with the Awards of Konteradmiral Otto Klüber

[Kriegsmarine Großadmiral]

List of his awards I have:

-Deutsches Kreuz in Gold am 20. 11. 1941 als Kapitän zur See und Chef des Stabes der Marinegruppenkommando Nord
-Eisernes Kreuz (1914) I. Klasse
-Eisernes Kreuz (1914) II. Klasse
-Königlich Preußische Rettungsmedaille am Bande
-Ehrenkreuz für Frontkämpfer
-Wehrmacht Dienstauszeichnung IV. bis I. Klasse
-Spanienkreuz mit Schwertern
-Spange zum Eisernen Kreuz I. Klasse
-Spange zum Eisernen Kreuz II. Klasse
-Finnischer Orden des Freiheitskreuzes I. Klasse mit Schwertern (21. 05. 1942)

Below is a photo of Klüber that shows some additional awards I think. I apologise for the bad quality of the photo but that's the best I can do.

Firstly, is the Spanienkreuz mit Schwertern the Bronze, Silber or Gold version? I personally think it is Silber because the version in Gold was harder to get (to my knowledge). It could also be the Bronze version.

Secondly, could the award below his EK I be the Flottenkriegsabzeichen? He was Commandant of the Leichte Kreuzer ‘Nürnberg’ (24 Nov 1938-07 Aug 1940) which would make him eligible for the Flottenkriegsabzeichen.

And lastly, to me, the 2nd to last ribbon on his ribbon bar looks like the Sudetenland Medaille (black with red stripe in the middle). Does anyone agree? If you think it is not the Sudetenland Medaille please propose an alternative.

P.S. I will also post the non-zoomed photo below. It might help.

Many thanks

I can see the Sudetenland Medal (Die Medaille zur Erinnerung an den 1. Oktober 1938).

To me, he is wearing the Flottenkriegsabzeichen below his EK 1.

Thank you guys!

If we believe Hildebrand, Klüber was captured on 20 April 1945. This would be a rather early date for a KM flag officer who was not holed up in a fortress. Does anybody know more (place and circumstances)?

Perhaps if we find out where the HQ of Amtsgruppe für Beschaffung, Verwaltung und Nachschub von Artilleriewaffen und Munition, Nebel-und Gasschutzgerät, Artilleriearsenale was. That would give a clue I guess.
