IIRC, the Traditions Panther was a basic plastic stockedsidelock/drum model with fixed sights anda single trigger similar tothe Traditions Deerhunter or CVA Bobcat.
The Centurion is a plastic stocked inline thatis thoughtto be a Chinese import made by Norinco. In 2002, Century had a special on these for $59 shipped to your door, although I foundone retailing for $99 now.

If the rifle is the same model as the Navy Arms Country Boy, then I doknowofone previousownerwho saidthathis was a very accurate rifle too. But I also recall a (Gun Tests?) reportthatthe modelhad a durability issue,however that may have just beenthe isolated reportof a poorly madegun (It was something about a bolt handle falling off or a similar probelm the first time a newone was testfired... it sounded unusual).
