This is a long shot, but does anyone know a fellow who purchased a BRNO .22 mag at an OKC gun show within the last two or three months? At the time I sold it to him I didn't have the owner's manual. I've since found it, but now I don't remember who it was. He was a middle-aged guy at most, and he was sitting with an older dealer behind a table. I haven't seen him after that.
