2. The '3 -Bank Targets' on the right are in a different position, kind of taking the position of the Captive ball in the production game. There is also an additional '3 Bank Targets' mid table where the single 'More Time' target is in regular game.
These targets are also solid '3D' style rectangular, as opposed to the flat circular used in production.
3. The ramps are plastic, not metal. They seem to be in pretty much the same positions. The left ramp returns the ball to the right flipper via wireform. The right ramp feeds to either flipper via a divertor . Not sure how this is used in gameplay.
Each ramp has only one 'shot indicating' lamp above it, not 2 as in production. Lamp is not labelled in any way.
4. The left Loop shot is a dead end in the proto. Instead of allowing the ball to complete a loop it now feeds the ball back down the top flipper.
5. The Genius lane no longer feeds the top flipper but ends in a scoop which via a VUK sends the ball up into the bomber where it drops into the upper pop bumper area. Cool ! When I originally saw pics of the proto I couldn't quite tell what was going on with the ramps/bomber/genius shot so its good to have this clarified.
6. There are no Spinners in the proto. Production has one in each right and left loop shot.
7. The right 'Union Jack Mode start' is a scoop with the ball fed straight back out, rather than a VUK to the right flipper as in the regular game.
8. A real Chime unit is fitted, and you can hear the chimes when the blinders are across. And during multiball.
9. Appears to be a Shaker motor fitted and running, again when the blinders are across. Maybe in multiball also (?)
10. No Captive Ball.
11. The shooter lane is not elevated. The ball enters at playfield level thru a regular gate.
12. Star Posts appear to be used - the regular game has the uglier plain DE posts. (So ugly I changed mine to back star posts : ) ...... )
The main differences in the Modes appears to be that there is no Captain Walker (video) mode - instead it is named 'Bomber Ramps'. And as the name suggests you have to hit the ramps.
This would appear to have become the Captain Walker bombing/ramp sequence in the regular game.
The 'Holiday Camp' mode seems to be 'switch hits' rather than the captive ball.
The Playfield artwork is similar but certainly different, as is all the plastic artwork.
The 'Bomber' itself is a very different design.
Different translite is used also.
