I'm trying out my friend's Centurion for a while and thought I'd add it to the database, as well as ask if anybody can identify the model.

Serial Number: M6C06314
60cm orange frame with chrome steering tube lugs and rear dropouts.
No model name printed on the top tube.
Suntour Cyclone drivetrain, with a Shimano 600 headset, Campy brakes (couldn't identify), and Phil Wood hubs... so obviously somebody built this bike up. I imagine the Cyclone drivetrain is original and the rest was thrown on a some point.

The seat tube has a "Champion Cro-Mo Steel" badge and then two rings about a foot apart that are:
Blue
Silver
Black
Yellow
Blue

Based on their condition I'm guessing they're original stickers but somebody may have added them at some point.

Anybody know what I'm working with? I've search the forums as much as I could but can't find an orange nameless Centurion from 1986.

Thanks!

ps- extra bonus points for anybody who also wants to tell me it's approx. value.
