I have to say that this thread would be infinitely better with a a picture as I cant quite grasp the description you have provided.
What I can tell you is that the minute register (the sub-dial at the bottom) has orange blocks for 10, 20 and 30. The hour register (sub-dial at the top) has an Orange block every other hour.
This is an original 6138-0010 dial (albeit an early one with proof markings under the day/date which changed to resist markings and then to nothing as the years went on..)
