I recently rediscovered that Atlantis has a unique feature where hitting two adjacent drop targets in the left target bank awards 5000 points instead of the usual 500 drop target value. I had a look at the schematic to figure out how it was done and think there might be an error in the schematic. My googling didn't find a discussion of this elsewhere.

The C/500 Point Relay for the White drop targets should fire when any of the odd/white drop targets is hit, along with a bunch of other things. But the way it's drawn, the C relay seems to be on all the time through the normally closed Motor 2B switch in the bottom right corner.

I think a normally open switch on the C relay should be in the long vertical line between the C relay coil and the Motor 2B switch. It would complete a garden variety lock in circuit to keep the C relay active (once activated) through a complete Score Motor cycle. Another clue is that the wire color at the C relay coil (blue) doesn't match the wire color on the Motor 2B switch (yellow+blue).

Or, am I missing something and the schematic is correct as drawn?

Extra credit and appreciation for anyone who can verify that a normally open C relay switch is really there in a game.

Thanks for the clarifications. My original is damaged in just the right way to remove the lock in switch. The scan I posted above is cleaned up some but also has a self inflicted transcription error.

Interesting nugget about the signature and time stamp too.

I was studying this circuit so I could simulate it and offer an explanation for those who haven't seen it. The results are at:
