How would you bend this frame back?

Wish I knew more about metal work. I'm such a babe in the woods, I don't know what "sister" means. This bow attaches to the top fabric. I'm guessing there is wood inside the (maybe) channel shaped bow to nail the top fabric to. I'd put a come-along to the sharp pinch point and pull it down a bit for a partial temp fix, but with my luck I'd bend something else that isn't bent now! :BangHead:
