Early Wind-Power downwind design

[WindFinn]

I'm new to the list. I thought I'd share some pictures of an early Wind-Power downwind model I got from a friend. He bought it at a farm auction about 15-20 years ago and never did anything with it. I kept bugging him about it until he finally gave in and traded with me for some tools he needed.

The bearings are froze up from sitting out side all these years. It's missing the fly weights for pitching the blades, but the blades are in surprisingly good condition for it's age. They were kept in dry storage.

There is no model number or ID plate on it, but Mike shared an old advertisement flyer with a picture of the same unit. It was advertised as a Wind-Power Dynamo. Does anyone have any specs or other information about it ?

Its a great looking machine.  I'm guessing the shroud and brush cover are aluminum?  You may have already seen it but here is a link to a previous related discussion.

Yes, the shroud is aluminum and corroded at the bottom. It doesn't appear to be as aerodynamic as the later Winpower models.

Thanks for the link to the previous discussion !

I’m fairly certain that the 2500W Wind Powers did not have flyweights. The mass of the blades were apparently sufficient.  You don’t see the flyweight indentions on the face of the prop, only washer indentions.  The props for my recently acquired Wind Power are identical to yours.  Also same round balance weights.

I didn't see any indentations in the blades from fly weights, so that makes sense. 

Any idea when these were made ?  Late 1920's or early 30's ?

I’d say mid 30’s.  Check out link below for more history on the company.  Can you tell what the original color was for the generator?
