It sounds like trembler coils. They use the magnetism of the coil operation to turn it back on so you end up with a continuous series of sparks when you have power. So the distributor will just connect power to it just after TDC but the power stays on a bit to get many sparks.

Of course, each spark is less powerful than a normal coil. Tremblers are great if the engine needs to run on any fuel imaginable, like 20 octane gas. A normal ignition system gives more efficiency and power but the fuel must be sufficiently volatile to deflagrate with the single spark. Makes sense for wartime use if fuel quality was intermittent. I see no real use in a normal postwar vehicle.
