Hi Luckeydog.
5 to 7 years ago, can't remember now? I purchased from Hydrogen Appliances a Hornet wind generator.
I never did get the preformance I had hoped for. The Hornet came with 3 blades that are an exact copy of the SW WP 403 blades accept they are a littel longer.
The Hornet was one of the first to market a wind generator based on a GM alternator.
They replaced the rotor coil with a large doughnut NEO magnet. Since then they have introduced a couple diferant rotors with small bar type NEO magnets.
They also now sell ther wind generator with 6 of there SW nock off plastic blades.
I didn't build this GM alt it is from my old Hornet. Now there are several Companies that sell the GM alternator based wind generator.
TLG offers the TLG Boast Buster as an upgrade blade for these commercial sold wind generators. TLG suggest the preformance of these GM alternator wind generators will be improved.
I was sent a set of the TLG blades by a fellow board member for testing on a GE ECM motor.
Since I still had the Hornet I thought this would be a good time to see how the TLGs preformed. The above #s are my results.
Here are a few companies that I'm aware of the sell a GM based wind generator.

Mikes Windmill Shop , Koolenergytools and Hydrogen Appliances use the Hornet blades.
Windblue uses a 2 blade built by TLG and TLG sells the upgrade Boast Buster blades.

All I've done here was tested these blades on the GM Hornet alternator they are suggested for and reported how they preformed for me in my test procidure.
The wind speed #s are scewed by the wind going over the cab of my truck but all the blades were tested the same way under the same conditions but the diferances are real.
These are not my blades or my alternator. I'm simply testing what this industry is offering and suggesting.
Personaly I prefure my blades or wood carved blades or foam pipe blades. I also prefure for small wind generators, motor conversion, GE ECM motors, F&Ps or best yet duel rotor disc alts built from scratch.
