The STurmey archer AW hub has been around for decades, it is a 177% gear range 3 speed hub with a stainless steel shell.

Don't do it, you could buy new for 10% extra!

10 - Shifter

Sturmey Archer 3 Speed Shifter: SLS3N
Wow! Quiet a list, the above will cost you around £35 from a bike shop such as Freemans. So if you add on the £15 you spent on your ebay purchase you are up to £50. Freemans will do an all in brad new hub with fitting kit for £55.

So it is not really worth buying second hand. 

Sturmey Archer AW Hub - Performance

With most derailure systems prodicing at least 250% gear range (1 x 7) or a whopping 700% for a typical (3 x 9) you will be taking a step in to history with this hub, BUT consider the lack of servicing, the hub's record speaks for itself with functional AW hubs still going strong after 30 years! 

Most modern Sturmey archer hubs are grease lubricated, which is a step backwards. High hubs such as rolhoff speed hubs are oil lubricated, as is the case with older sturmey archer AW hubs, one reason perhaps to buy second hand . . . . .
