Hi all, I have what I believe to be a Claud Butler Elite 531 with Campagnolo Avanti groupset that I picked up and fixed from being in a pretty sorry state. I believe it to be a CB ELITE 531, based on some of my own research, the only sticker left is the one with the frame number on it, there's no serial stamped on the actual frame. The Campagnolo sticker was added by me. I've also included a picture of an Elite 531 I found during my own research. I'd appreciate any help in identifying the bike.
