Identify gt dyno

[Scottlock]

Hi all, any chance anybody could give me some info on this bike, I know it's a GT but I'm curious on model, age etc. A cousin gave it to my son years ago its been sat in the shed for most of the time now he wants to restore it, I just want to know if its worth it, cheers

[GavinDavis]

Definitely late 90s there fella!  Looks like a Dyno zone or the likes....

Possibly around 1998

 Thought we were on a winner for a few minutes, don't know much about GT's it is quite heavy, the zone and dyno compe look so similar, cheers guys
