Quoted from xTheBlackKnightx:BLUF: You may want to include additional details and the underside of the Dalek itself, or reword this ad title.
I do not see anything remarkable about this topper based on what is shown.
As seen in the listed photos there is no fully machined assembly, no motor, no wiring, no connectors, no head with proper extension post or baseplate, and the dome is the factory standard from the production game.
It is missing everything.
Prototype toppers are completely different.
It just looks like a topper from a standard game, using the correct mold, although uncommon to acquire today.
The WMS factory overproduced toppers as well.
As a I own a second version prototype direct from the WMS factory, and there are two game prototype versions.
The first version only had 4 games made, and two exist today, and used the WMS System 11 cabinet, lithograph, and translite.
The second version had less than 15 games made, and most were converted into early production sample models using the BLY cabinet and original translite cutdown, wiring, and prototype doctor light board.
There is a third early production model (around 100 games) which include the game samples which get often identified as prototypes improperly, simply because they have a moving motorized Dalek head.
That was not a prototype.
The remaining production topper was for standard games, as shown in these photos for the Dalek.
I too would love to know the differences. I own a Dr. Who and it has a moving Dalek head. I did not install the parts and I know for sure the two previous people that owned the game before me did not modify it. I have looked at it before trying to figure out if it was one of the 100 spoken about games that are samples. Is there any info you can provide me to see if these parts were added or if it came from the factory like that?
