This prop actually seems to be made from two different Dalek models.
The bottom half is from the first half of the Dalek episode when the Dalek is chained up, it is only after the contact with Rose that it tidies itself up and later we get to see the inside.
Quite an impressive prop and again looks really good close-up.
I thought that they did a very good job on the new Daleks and I really like the design.
