I think they are called Turbines, I just bought this set for the 510, hoping someone could give me any information on them.

They are 14"x6.5"

 

At first look, my last remaining brain cells screamed "Appliance Wheels"

But, it goggled Appliance wheels and came up with this link.  http://vintagewheelcatalogs.com/

Thanks to the creator of that website for preserving vintage catalogs!

What a great site!

OK seems like they are Western Clyclone II

Rocket Wheel?

Circa 1979?

Crager made some also, from 1979

look like american racing vectors. https://duckduckgo.com/?t=ffab&q=american+racing+vector&iax=images&ia=images

Note: the number of fins can vary.

They're not American Racing Vector. I have a set. I believe all the Vectors were ten spoke.

Western Cyclone II, 15 spokes, now I just have to find caps for them.
