Hi Myles. I’m assuming you signify the album has the Side two tracks pressed onto each side, and not that there are simply two Aspect 2 labels within the LP. I’ve hardly ever observed that kdr prefix about the catalog amount just before; are you certain it’s not ksd? https://ledzeppelingoldrecordawar58851.blogdanica.com/26658716/led-zeppelin-gold-records-an-overview
