Roy's correct, I don't know what I was looking at.

Parts 1, 13 and 14 tend to stay fitted to the cylinder.
first bolt part 2 to the cylinder.
then slide the odd square washer 12 onto the shaft, note it doesn't slide all the way down.
the butterfly 4 is next
then washer 10 (which is big enough to go over the shaft and but up to the butterfly).
then washer 11 (which is smaller and stays on the threaded part of the shaft)
then the l/h threaded bolt 9.

I have no idea why it's done like that, it's vastly over complicated. They probably didn't replicate the whole RS method as that needs maintenance (it's rose joints need lubing) and it'd cost more but they could have done a better job than they did.
