Not to start a further dispute, but I have a Vitus (MK1 979), but think this one might actually be a Peugeot Comete - As Vitus didn't use any bolts like this on the seat tube/rear triangle joint, this one also doesn't have the same rear brake mount as the more pointy Vitus' and it also has non-vitus forks...
Hope this helps!
