During the 40's thru late 60's there are many Voltage regulators labeled "+ grnd" or labeled "- grnd". Also a few generators and maybe other parts. But voltt regulators labeled for specific + or - ground is rather common.
I have NEVER seen an ignition coil labeled + or - ground.

On a different note:
So IF a + grnd ignition coil has core windings wound (let us assume) opposite clocwise while a - grnd coil is wound clockwise then the only differeence between the coils would be the "+" and "-" LABELS on the coil posts. No???

So then using an UNKOWN coil then it would only require to determine direction of windings in the coil (using somekind of test equipment) and then connect the coil to be compatable with the polarity of the car.

No???
