My first question is, is there a difference between the discs with the square cut in them as opposed to the round cut?

I know that early Abloys had a round sidebar and the later ones have gone to an L-shaped sidebar that can't be pulled. Are the round cuts only for the round sidebars? In looking at Gordon's post about re-keying the Abloy, he seems to have both cuts. But the square cuts seem to be on the ends. I can't test to see if the square ones have enough clearance because I have a cam lock that is missing its sidebar. Does anyone have the diameter of the sidebar for this lock?
Question 2: Is the bottom left disc for the bottom of the stack? If so, why the second cut that would clear the sidebar when in the locked position?
Question C: Am I correct in labeling the other two "closest to the bow"? Why is one brass? Why the second cuts?
I believe my kit is complete, I have the spacers and the locking springs for the ends of the plugs. Just that I seem to have 1/3 the amount of the square cut discs compared to the round hole ones.
