If you join Paper Modelers website there are quite a few free small diesel downloads that are available some of which are fairly simple. You will also see state of the art paper modeling, as good as that beautiful Lister. Some are simply unbelievably great! I have a couple that I started, but with Steve Bennett making his resin stuff again at pepper7, I have gone back to easier modeling. Paper takes quite a bit of work, and I am getting old and lazy.
