Re: Which Voltage Regulator?
I have not done anything with a generator in 40 years.
IHC in the early to mid-fifties.

In some mfg and applications, they used a "third brush" system to control the current and in some cases voltage as well. Early Chevys were that way, it is a cheap system and is used when the current need is low and cost is more important then output control.
Alternators are self limiting for current and only need a voltage regulator, so one can fit many different alternators.
To answer the question "how do I know what current generator I have" the best way is to look up the tag number.
If the tag is missing there are a few guide posts to make a estimated guess. If the generator case is all the same diameter all the way back, and the brush "windows" are covered with a sheet metal band AND the case has the field poles held in with a single screw for each shoe, then the generator is a 30-35 amp unit if 6 volt or 25-30 amp if 12 volt. If the case is narrower (smaller in diameter) at the brush end and there is no sheet metal band or access windows for the brushes, then it is 42-46 amp if 6 volt, 35-42 amp if 12 volt.
If the case is large diamenter, has a sheet metal band AND has 2 screws holding the pole shoes on, then it is 50-55 amp for both 6 or 12 volt units.
If the tag is still there but not readable, black tag is 6 volt, red tag is 12 volt, orange tag is 24-32-36 volt
