If I’m not mistaken (and I may very well be), InterNature bows were made my Samick. They were marketed under a bunch of different manufacturer’s names (PSE for example). That little wire spring arm doodad is called a flipper rest. Personally, that’s what I use. As far as strings are concerned, I would stay with B50 Dacron, because I don’t think they were FastFlight compatible. You could always take your existing string to an archery shop and have them spin another one. Otherwise, just tell them it’s for a 58″ AMO recurve.
