The Stovebolt Site Forums The Shop Area Engine Shop 216 coil ?'s

Here is something that I would like some history and education on…
(It’s a ’40 ½ ton, and I got it as a box of parts… disclaimer)
I have an ignition switch that has a cable looking casing around the hot wire, down to a chrome cover, that goes over the bottom end of the coil. I have three different types of coils but I would say that these two parts go together. The coil also has a stud and nut on the top end of the coil, where I would expect to see one (being a first series Camaro guy).
Questions:
1. Does this set up go to my ’40? I haven’t seen it in a lot of engine Pics.
2. What wire goes to the stud on the top, if any?
3. What hole in the firewall does the cable go thru?
4. Does the coil point down or up? I’ve seen both ways.
That’s it.

Thanks for the help.

It is an Electrolock ignition and some form of it was used in 1940. The flat end of the coil goes up with the armored cable attached and wired to the ignition input. The pointy end goes down and the HT lead goes between the coil and the distributor. The LT wire from the distributor usually goes to a stud next to the HT lead on the coil, but I have seen it at the other end on some years. There should be a fairly large hole in the firewall to the right of center and the cable passes through a grommet in this hole.
