Interesting.  Are you sure it wasn't "CB" and "SW"?

There is an old-time test for coil polarity: With the engine running, hold
the plug wire a bit away from the plug terminal (or any ground) and the tip
of a (sharpened) ordinary "lead" pencil in the gap.  If you look closely,
you should be able to see that the spark is brighter to one side of the
pencil tip.  If that side is towards the plug/ground, the spark polarity is
correct.

There is a better write-up (and another method) at
