This list is simply a list. No account has been taken of the complexity of the model nor of it's author etc. Where you see a number after a name, it means there is another model out there with the same name, but of a different design. All links are external ones and go direct to either a jpg/gif/html image or a pdf download (for which you will need Adobe Reader, if you haven't already got it). No model diagrams reside on my website, they all reside on the creator's website. Of course, some links may go to sites in which the diagram has been placed without permission. I deplore this, but I am not psychic enough to discern between who has or hasn't obtained permission!
