Mystery Ignition Box

I appreciate all of the input and advice, I'm having my dad take some photos of the underside of the box tonight to see if there's any identifying marks (the car doesn't live where I do currently). For the ignition backup, I found a brand new single point distributor for $40... I didn't realize how easy they are to wire up, but seeing as it's literally one wire to the negative on the coil, I feel pretty comfortable making that "repair" should it be necessary :D
