Getting a headstart here so I don't have as much to put up later when I start testing.
These are the Fisher & Paykel parts I have purchased. I'm buying all new stuff so I have a known good starting point. These parts purchased in Australia. Prices are in Aussie dollars.

Still missing the part which the 2 bearings sit in, and bolts to the stator, called a spline. Should arrive in a day or 2.
I have no idea what model(s) these parts fit.
The stator has 42 coils, connected as a 3 winding star. The resistance of each is 6 ohms. One end of each coil is brought out to a spade terminal. The other end of each coil is also terminated in a smaller female spade terminal, with a 3 pronged metal link to join them together to form the neutral point. So it would be fairly trivial to rewire it to delta if one so desired.
The plan is to not rewire the stator. Transmission of power from the tower to the battery bank will be high voltage. 3 toroidal transformers will transform the voltage down to 12 volts to charge the batteries. Toroidals should be better than 90% efficient. I'm expecting somewhere between 300 watts & 1 kilowatt out of this generator. At 12 volts, the line resistance to move that much power any appreciable distance (efficiently) becomes ridiculously small. And expensive.
The toroidals I have chosen are 250 VA each. They have 2 primary windings of 120 volts, and 2 secondary windings of 9 volts each. It should be possible to choose a series or parallel connection setup to match the generator. Maybe even a change-over relay for light wind / heavy wind. I purchased these from Oatley electronics for $25.00 each. They are mounted in a 2 unit rack case, although the bottom of the rack case sags with the weight.

Enough for now, photos tomorrow.
