I've always thought the same, is a very weird way to lay down the colors, like you said, they changed their mind, maybe color wise was too close to the others. I know the makers had carte blanche to build them.
A lot of the photos are out there NOW, but it took a very long time for those photos to get release to the public since a lot of them had to get scanned from the people who own the hard copies and they refused to share until a few years back.
And i am very glad they did.
