We have a winner!

Miss Gene will now put a bronze star on your forehead right where you have been trying to make holes in the concrete floor.

(Ok, I'm a bit sleep deprived.)

The ARC5 manual lists the color code as:
  85 kc brown (looks black to me)
 239    red
 705    orange (these two can look very similar especially if it's dusty from storage)
1415    yellow
2830    green

The ARA/ATA manual does not have a color code. The drawings specify there should be one. The photos do not show any. Indeed, I just went through my stash and some of mine do not have a dot.

Of course, the answer whether or not the 1st and 3rd have been interchanged might just be as simple as looking at the part number.

Duh.

705 kc
1st 7271
2nd 7272
3rd 7273
