There where 4 prototype Styrofoam models made.
All had a "snub nose"* (really an eye, not a nose!)
Can you guess who won the "Beauty Contest"?
The Winner! #3
Here he is with real parts & paint!
This is what you get when you order Dalek under Glass at a restaurant???
* The "snub nose" was made short because it had to fit under a protective plastic dome.
(to avoid mischievous players or dedicated fans from pulling the Dalek eye out)
And the width of the top of the backbox is very narrow!
