I have an ancient motor and would like to get help wiring it up safely. I found some good information in these two places, not it isn't specific enough for my situation: Old electric motor wiring question. - Electronics | DSLReports Forums

I got this at a farm auction, so I don't know anything about it. There was one wire on it, connected to the fourth terminal (left to right in the picture below). There was no male end on the wire--no plug, so I don't know if this was 220V or 110V or something else.
The badge on the motor says:
Henricks Magneto and Electric Co
Indianapolis, IN
Type: D20
No: 1142
Volts: 30
Amp: 20
KW: 0.8
RPM: 1800
Its about a foot long and 10" in diameter. Weighs about 80lbs.
There are two huge brushes and no capacitor. From another thread, I think this might be a repulsion start 2 pole motor.
Looking at the commutator end, there are four terminals (left to right). #1 and #4 are larger and are wired to the brushes. #2 and #3 are smaller and lead to the windings inside the housing. Terminals #1 and #2 are connected via a copper plate. Another one could have existed between #3 and #4.
There is one wire connecting the two sides of the windings in the motor at the arbor end, which I need to re-insulate. I've pulled the stator to clean and regrease all the parts. All the bars look decent. Most of the wiring and epoxy looks intact.
I'm wondering how to wire this up. I have a multi-meter, but am a complete novice at using it.
Any information/resources, etc would be greatly appreciated.
