thats a find, I've looked for years and never came accross one. I once got 200 tinsquids and brass eyes and stuff to make then but never could find a mold. if there out there people ain't selling them. I'd love to see a picture.ed
My friend has a mold like that with a post/pin that holds the hook.hard to find the right size hook for the post.He carefully opens the hook an slides it around the pin an closes it.I think the idea behind that type was the hook with the feathers is supposed to slide around on the cast for better distance..he has a few nice ones with scales on the top.Good luck.
