The Ford Barn

I have a Ford R3 generator believed to be a ‘37 or ‘38, that was recently rebuilt - bearings, brushes, armature etc.
I have yet to get a new cutout due to needing 12v to power the conversion bulbs for the carbide headlights.
I am not familiar with this vintage generator so I have a couple of -

Questions:
1. Are all generators of this vintage positive ground by design, or does the cutout and wiring dictate + or - ground ?
2. Can the conversion regulators from Fun Projects ( http://www.funprojects.com/products/10505r.aspx ) be used to get 12v from this generator ?
3. If so, positive or negative ground ?

There is no starter, and ignition is via magneto, so electrical usage is minimal with only lights and ammeter.

Would appreciate your input.
