This specific shape of longcoat (the one that closes rather tightly near the chest) the klicky wears didn´t come in black before
It looks to me like a run-of-the-mill long coat, the one that only looks nice on a fat clicky.
Apologies for my uninformed comments. In fact, I believe there are currently 3 long coats around:
1. with collar (top row left)
2. without collar, tight around the neck (top row right)
3. with collar, ripped (bottom)
You were saying that type 2 did not yet exist in black, which I don't know.
I still believe the concert master would look better in a tailcoat.
Best wishes
