Coticule layer ID please?

[king]

So, there are photos of the Coticule from my friend. He told that he bought it as a vintage one few years ago. The photos are not the best quality but maybe someone have idea of the layer. Btw. dimensions are 120x50x20 if that means something.
Thx

Gary i don't thing so is an old rock coti. My heritage one is very pale without any spots or stains.
The pale color is the characteristic of old rocks.
