I've been watching the Netflix series The Protector for the last time, and since the protagonist stung my leather jacket in the eye, I could tell you where to get it or what the brand is called
You buy a leather jacket, maybe even a flea market and glue such patches on it…
The exact jacket itself will be made specifically for The Protector and will not be available for purchase, but there are very good replicas that look just like the original, there are some shops on the internet.
Just enter tags such as "The Protector leather jacket" or "Hakan Demir The Protector jacket" in Google, because you will find different suppliers who also ship to Germany.
Hope it helps.
