A Friend of mine makes 3D Digital Models for a Railway Sim, Trainz 2004, and he is looking for Scale line drawrings of any form of road Transport buses mostly.
You can see some of his work here....

If you have trainz 2004 all the downloads are free from the site, if you do not have it, Why Not?
If any one has any please PM me.
Many thanks
