 Tell me more about Jim Sullivan. You mentioned him earlier. He was still alive and still alive, I think, now. So you were able to talk to him in researching this book. Yeah, Jim Sullivan. So we, you know, in doing this history, we sought out original sources, right? We were able to speak with Stoner's family, get access to his personal papers. And Jim Sullivan is the last living member of this Armalite team who worked on this gun. So it was really important that we spend time with him.
