Coils were marked after the 12-volt era had set in pretty well. Back in the 6-volt era, there was no need to differentiate. The coils used in the late 50s where 12-volt had taken over were the same as the older 6-volt coils but they used a ballast resistor to control the amperage going to it.

The 1941 cars still had the old helmet type distributor on the front of the engine. These types had the coil mounted to the top of the distributor. Some may have been converted to crab type distributor or converted to a separate can type coil set up. There has been a lot of water under the bridge since then. It could even have an 8BA engine in there for all we know.
