If your frame is made of Thron tubing I think Thron was a mid 90's tube set made from the older Cyclex tube material. It is double butted and probably aimed at the amateur racer looking for a competitive frame.
I think your Colnago's identity probably lies in the mid range of models from the mid 90's era.
Yeah thanks for the reply, from my own research I dated it around the early to mid 90's. I guess it is a guess until colnago finally come back to me if they ever do.
