Ritterkreuz des Eisernen Kreuzes ribbon to ID, please.

Hello all,
just got this RK ribbon, does it seems ok to you?
It is 15.5 cm long.
No lightning up under UV, it feels good at the touch (like silk...), and compared to my ekII ribbons; a quiet similar construction...

Hello again, I posted it on four different fora, but didn't get any response so far...
I assume it is good; but hard to tell.....
