In the interests if full disclosure, I was very 'inspired' by this page (at least for the legs anyway...)

I've surprised myself with how the proportions seem to be somewhere near. Did start to look at a 3D model of the real thing and decided I couldn't be arsed and did the thing any self respecting Yorkshire man would do. I eyeballed it :Y
I think I've made it too long though. :$
Can't beat a bit of eyeballing :C
I did the same for everythign above where the legs meet on the tower :D
