Here is a neat little 12 volt Wind charger from the 1940's.

They are designed to tilt back up out of the wind. I found this one on top of an old barn, complete except for the prop.

Amazingly it wasn't seized and took very little to get it operating again. Two new bearings and some cleaning. I was amazed when I opened it up to find everything still functional.

I tried to keep it as original as I could right down to the original screws. However the prop is just one I've had hanging around for years, it just kinda suited it. The tail should have the Parris-Dunn logo on it too.

The most amazing thing I think is the tower legs are all aluminum, light as a feather yet after 60 years still not a crack or bend in them!

I was getting good voltage by hand, but noticed one set of brushes is cracked right through so will change those, otherwise it motors up with a battery. More info can be found here:
