Plaque to KC Prinz Eugen Captain

[Venturii]

 

Some years ago I got this plaque with some other items. Its a 15cm diameter brass plaque with a text wishing Helmut Brinkmann congratulations with his KC from Stab Marine Gruppen Kommando Süd. 
Brinkmann was captain on the Prinz Eugen and later on CIC Black Seas fleet.

Have any of you seen something like this before? Fake, real, etc. Any thought?

Thank you / Hans

Interesting plate, but, IMO, very hard to say anything more about.
