Help please - Buckle converted to brooch

[StuG III]

My wife found this somewhere and bought it for me. I however do not know what it is. It looks like an old buckle that has been converted into a brooch. I cannot even place the origin of the piece, crown could be Belgian?? Please have a look and tell me what you think, thank you.

Tom, it is a a buckle, but not IMO Imperial German ....however the fastner, pin/hinge and hook are of a German style, commonly seen on EK I (1920's/30's) and TR combat badges !.... I show an Imperial Kaiserliche Marine Officers buckle for comparison....

I have a thing called a "Hate Bracelet" that is made from British sholder board pips - by the Germans. Maybe that is what this is. A German killed the man wearing this buckle and made a trophy out of it. Makes a nice story, anyway.

Nice buckle.
I thought the item wasn't German, so maybe the idea of it being a war souvenir isn't that far off, hence the German hardware.
