Additionally I'm finding some Aermotor 702s with completely blank vanes (a few have been on the ground so I can examine them closely, there's no faded lettering), and typical curved-V shaped vane braces.

I wonder if these perhaps came from a different rebuilder than the rebuilder doing the pointy ...

Thanks for confirming that the V brace on the older models is indeed not really a V but more of a U.
All these replies have been so very helpful and educational!

Thanks Ron, that was so helpful!

Wow that's really interesting, now I know this is definitely a thing, altho what kind of thing remains to be determined.
The Field Guide specifically says the Pumping Aermotors had a V shaped brace. Maybe some Pumping Aermotor vane braces were pointier than others?
Thanks for your reply!

Hi -
On 2 separate properties within 20 miles of each other outside of Denver CO I've seen an Aermotor 702 with a vane that had a distinctly V shaped vane brace in that the end was pointy, not curved.

The Field Guide says the Pumping Aermotor had a V shaped brace but the drawing on the section head ...

Hi Everybody -
Does anyone know what this might be? It looks like a Currie fan on a Fairbanks body. The vane says Fairbanks. I'm guessing someone put some unrelated pieces together to make an ornamental installation. It's in somebody's yard so I can't get any closer.

Thanks
