I've got a Turner, last of the HL - late 05. Pm me if that is the type with your requirements. Have you tried emailing Turner, they are very helpful, Dave Turner may reply himself - he did when I contacted them..
Have quite a few Turners and the downtube decal size varies a little over the years. If you are after custom ones there is a guy in the states who can make up whatever you want and they are excellent quality.
