Missing: Belt buckle

[Flieger]

Call me blind, call me stupid, but somehow I didn't notice that ¬?-part of the belt buckle on my German leather jacket was missing until today!

I guess finding a replacement will be difficult, but I hope someone here might know what the missing part looks like so that I can look for it or "MacGyver" my own.

Here's a photo of the part I have... the leather show traces of the missing part.

Cheers
