Technical notes:

Chain tensioner / gear indicator nut:

(This is the nut with a hole in the side)
Later hubs 2003 onwards (normally with alloy shell) use this nut.
The difference between this and the pre-2003 steel shell nut may be small - but it is essential to use the right one. 

Brompton reference: QCTN3-SA
