It's a stretch between the Carolina's and the Canadian prairies, but you're welcome to have a look at my ECO 6. There is an ECO 6 in Florida built some years ago with the original shaped bow. The builder is not a member of this Forum. He was on Facebook back when I started building and even set up a Facebook page for the ECO 6. ?He and I communicated a bit but he dropped off Facebook and deleted the page. I don't know how you could contact him.
