I expect Silent Invader might make his patent rules available at some point...

Just need to work out how to expand them from 2 brilliant pages into 100 pages of padding, photographs, waffle and bullshit to justify a properly exhorbitant price tag

(Sorry, as you can probably tell, I have something of a downer on the current trend for profiteering from big fat glossy rulebooks!

)
Thanks to all for the comments. Rematch in a few weeks!
