Can we get a definitive answer between us as to how to identify each of them?
Here's my take.. Very simple

a) coils for 12 volt non ballasted ignition circuits ---- will show 12 v out when put from one terminal to the other
b) coils for 6 volt ignition circuits ---- will show 6v out when 12v is put in one side
c) coils for 12 volt ignition circuits with a ballast resistor ---- will show 6v out when 12v is put in one side due to the internal resistor
d) so-called sports coils for 12 volt circuits ---- will show 12 v out when put from one terminal to the other.

Hope this Helps.
