O.K. managed to find a high-lighter to out-line the scale(s) in question.
EAST...

Notice how the 3 scales in RED are touching
WEST....

Now, look at the scale in yellow on this animal. This separates the 3 RED scales.
I know of breeders that got some of Caseys "west" animals that turned around and breed them to the animals in their collection, which were most likely east or NT animals.
I'm certain that if an animal with the extra scale breed with an animal that didn't have it....that you would get a combo of both types in the clutch.
This is what I would like to find out.
