original IH Ignition coil question

I have 2 original IH ignition coils, that I have long since forgotten the voltage on. I do remember one is 6 and the other is a 12 volt, but again don't know which is which. What would be the resistance (ohns) on the 6 verses the 12? The same question on the lights for my 53 SM (pancake type). Reproduction 12 volt verses original 6 volt. Thanks
 
Easy One will have 1/2 the resistance of the other. One around 2 ohms the other around 4. (approximate) The higher Ohms is 12v. JimN
