Well, I'm gonna carry on about the Refugee beans again. Love em. First got them from Russ in 2017, they looked like the ones on the right in the picture below and the two to the left grew as off types that year.
i'm not 100% sure about the "small flat" they may just have been an environmental variation.
I think Russ's original description of them was that they were one of the first beans used when commercial canning started. The by chance I came across this picture, dated to late 1800's. I'v posted it before but it is so neat, here it is again.
Refugee beans popped up again when I was doing research on vine growth habit inheritance in beans. You can read about it in this paper from 1915.

seq=1#metadata_info_tab_contents, some interesting stuff there, I think.
Last year, 2018 I only grew a small patch and we ate most of them, nothing out of the normal showed up in the seeds I did save. This year I planted some of the off types from 2017 and his is what I got.
They all had purple or purple streaked pods, which we do not like except for the brown ones. Those pods were much longer 6 - 8 inches with lots of seeds while the others were not more than 4 inches. The brown seeded pods were a nice green, no purple at all and the brown ones far out produced all the other put together. The all did pretty good and were well behaved at about 5 feet tall with considerable side branching. I think they might produce best if spaced at least 8 inches apart, maybe a foot.
The others will get included in the back garden mix next year but the brown are going to get a good sized grow out. I'v named it Escapee for now.
