Does anyone know the whole First Devon and Cornwall bus fleet list?

I am doing a project for college and need to get information on current fleet vehicles so that i can calculate emissions and various other things. the latest one i could find was for Truronian in 2005 which has now been totally swallowed by First, who will not tell me anything. i am only concerned with busses operating in Cornwall (Route T34 to be precise) if that helps as they don't tend to get moved around very much. Please help if you can as i am running out of time.
