Finished reassembling the generator and tested it out. It puts out almost 2.0 volts at approximately 2000 rpm (or whatever my 20 volt Dewalt drill does) which is less than my other Stuart generator (2.4 volts) but I am extremely happy with it. My guess is that the wiring is original and very old as the Stuart 500 boiler has no bushes and the S-50 is a solid crank disc, all probably late 20s or early 30s. Now to sort out the streetlamp and the piping. Here is a picture of where I'm at right now with the steam plant.
