From researching October beans/Appalachian beans. I think that the region is fairly small and not particularly interested in putting information on the internet.
But what I gleaned is that Fall beans are often family heirlooms, sometimes thought not as tender as more standard beans, and can be used from small as green beans to shelled fresh to left on the plant until dry in October and then stored for winter.
I would plant a few four months before frost and see how they do over the summer/fall. Only investment is a couple of seeds, and you might get enough beans for a salad or soup. Then you can report back in this thread and the next person looking will have much more information.
