I just received some coil cores and this one was in it. I believe that the parts have been soldered on to the original posts, it does have the "Ford" script on the side of the box. Interesting, and I wonder why they would have done this.
Do you think It could be returned to stock?
Probably modified to run a hit and miss engine.
Fencer coil, might work again as a normal coil, but fencer service generally was hard on them, but you have nothing too loose.
Spark plug test fixtures?
I believe that coil is set up as a fence charger. I have found remnants of coils hanging on rural fence posts set up in a similar manner.
...And electric fencers have the same problem as repro T coils.
My 3 year old solar fencer quit working about a year ago and with my limited electrical knowledge I was able to narrow it down to one circuit board which I was able to order for $40. While I was waiting for the new board to come in I had the old one on the bench and noticed it had the a small, flat, brown capacitor just like the ones that fail fast in the repro T coils. I looked at it and sure enough it was .47 uF. I un-soldered it and soldered in an "orange drop" Model T coil capacitor and the fencer worked like new. Unfortunately the new board was already shipped at that point, so now I have a spare on the shelf.
There you go Adam. Contact the company and tell them you'll do board repairs for them to build customer relations - at $50 per unit.
An opportunity lost is a lost opportunity!
A lot of them were used on more modern cars as "shockers" too back in the day. Dave
The T coil fence chargers I have seen had a neat little device attached that had a marble or ball bearing in a glass tube that would somehow roll downhill in the tube, open the points and be knocked back uphill and this would make the fence charger 'pulse' on and off. I don't remember the details, but I wouldn't think a T-coil would last long if allowed to buzz continuously.
Here's some examples of the devices described:
Here's a video of the pendulum approach in action:
Very Interesting. Thank You gentlemen.
Fence Charger Coil
Do a search on LeJay HiBall Fence charger and you will find the instructions for the unit Ron posted above. It uses a marble rolling up and down the test tube instead of a pendulum.

Here are a few interesting used for a Model T coil.
