That is definitely the Prussian Empire (German) crown. Note the five ribs, with raised dots in the ribs, and the "horizontal long diamonds" on the headband. Here's a photo showing a World War One era German army uniform button. it is clearly the same crown as Zmermarine's, except for having a tiny cross on its top.

Did you dig this? Where/How did you get it? That's a pretty cool item. I love the patent on it.

I bought some sterling silver from an older man and this was one of the pieces.
