It's probably one of the German market models. They put "Centurion" on the top tubes of many models. From what I can see, it looks to be late 70s to early 80s. Maybe '79 to '82??

I believe those are Dia-Compe, from right around 1975-76. Those came stock on the 1975~76 Centurion Semi-Pros, but they switched to tacky black plastic clips by 1977.
