That's a great description for some half-runners!
Here are a few heirloom kinds: http://www.heirlooms.org/store/c13/H...ner_Beans.html

Hope your Pink half-runners do well this season! Here's a pic for you to look forward to:

and I just found there's one called "Volunteer", developed at the University of Tennessee, so of course I'll be looking for that one, now.

MuddyBuckets, this place doesn't ship to the US or Canada but they have a plethora of runner bean varieties, including the ones you're interested in. Perhaps you know someone in GB that could arrange an order?

I haven't grown any runner beans but wish you luck with growing them in the South! Maybe a little shade under the patio would be good?

One odd thing I just thought of: Why are half-runners the only beans without "beans" in the title?
"The bush beans are early this year."
"Wow, those are some really nice pole beans."
"Look at those beautiful runner bean blossoms!"
