Sorry but this looks like a ripoff
But this cap is pretty much a contemporary standard issue german navy enlisted dress uniform cap with an eagle and a swastika attached.
The cockade is today's german, not WW2 german, gold-red-black, it should be black-white red.
Also, the Mützenband should read "Panzerschiff Graf Spee", not "Schlachtschiff"
They haven't changed for 100 years or so, except the insignia and modern things like plastic labels.
I have the same model from my service time, only without the eagle and the swastika, of course
