Yet another coticule ID

Well, I picked up a dirty old coti and got it cleaned up and lapped flat today. Any idea what I've got here? It is not a natural combo, but is glued to some nice looking BBW. For reference, I've got a couple of pics of it next to a La Grise. Also, the color doesn't come through the camera quite right...rather than a dull gray, it's more of a greenish tint to it and some of the darker bands have a green/blue tint to them.Attachment 294815 Attachment 294816 Attachment 294817 Attachment 294818
