Khai wrote, "seems the BBC have plans for the Dalek.." In one of the short video vignettes, one of the series' designers talked about the various color schemes considered. He held up that sheet to illustrate his point. Eventually, they decided upon the 2nd from the upper left, the "bronze' tones. So those were simply color schemes that were rejected. Also, if you look closely, it's not the final physical design, anyway. The vertical panels surrounding the "chest" don't have the recessed paneling the on-screen prop has. I don't think these are meant to be the Daleks that will appear in episodes 12 and 13. But, I could be wrong. Sincerely, Bill
