Boaterbob is correct, you have a Pertronix ignition. The last photo shows the Ignitor module in your distributor, but it's old. Per-Lux changed it's name to Pertronix in 1991, so it's performance may be suspect. 25 years wouldn't be a bad life expectancy.
The black Ignitor wire goes to the "-" on the coil and the red goes to the "+". A switched 12 volt source is also attached to the "+" terminal of the coil. This cannot be the original 12 volt coil wire because that had a resistor to drop the voltage once the engine got running. Pertronix needs a full 12 volts all the time.
If it's not working, consider getting a new Pertronix for about $75.
Hope this helps
