Ok, I have been doing a bit of research tonight on these old ignition coils, and have found some pretty interesting things, as well as some really funny mean pranks that people used to pull with these...
I also think I now know why the previous owner had these, and really wish I could talk to him, so he could tell me how to wire up the big box...
I found an image of some boxes that were remarkably similar to the big box i have that I still have not been able to identify. the photos that I found had more contacts than mine, though the contacts had a lot of the same markings on them as well (Int, GRD, one left unmarked, which the website author seemed to think was the high tension contact). what I found was an atwater kent ignition system. turns out atwater kent was much better known for their radios than their ignition systems. a lot of their radio designs are very similar in construction to this box, though i am now sure this box is some sort of coil, or master coil for the smaller ignition coil boxes in my videos.
here is the link to most of the most interesting uses for these coils. some of this stuff is pretty funny, some of it apparently now illegal, and some of it fairly useful if you are into radios...
Model T Ford Forum: Unusual Uses For Model T Ignition Coils
I did find one website that said these old ignition coils could be used to repair old audio transformers. turns out that the HV would arc from broken wires in the transformer, and could create enough heat to basically weld the contact back together internally. sounds dangerous to me, but it must have worked well enough that it was fairly common practice.
I found several sites that all said these coils were also used as components in some Radio B setups? (forgive me, I am not very well versed in radio history) which would explain why the previous owner had these coils, much of the gear he left behind was old radio equipment, and there is even a radio he built from scratch down here that still works, though it only gets one station, and not very well
it seems he was likely using these in some form of radio setup, and also might explain why none of these have solder on the secondary contacts, as the photos I saw of them being used in radios didn't use this contact point either.
some of the more funny stories that i read...
high school seniors hooking a coil up the the iron hand rail at school on halloween when there were other students going through a haunted house setup. grab the rail and get a pretty nasty shock
one gas station owner who apperently got fed up with the local boys peeing on the side of his tin walled gas station, and hooked one up inside the shop so when the young fellas started to take a leak....well you can fill in the rest
there were several other prank stories, but most of them go along the same lines, bad suprise for anyone who put a hand or leaned on the wrong place...
a lot of it made me laugh pretty good
and judging by the prices you can find these things at on ebay, they are not uncommon either. I found some selling for less than $10 and in better shape than mine are in.
I still haven't identified the large box, though i have a much better idea of what it likely is, and I also have a clue that the contacts marked INT might just stand for interrupter, which would be quite useful if i can find any kind of wiring schematic that has similar contacts on it!
my quest continues...
