Includes the original 1902 3-speed, the popular K type of the 1920s and 30s, the T and TF 2-speeds, the ever popular AW, the SW, SG, SB, AB, AG, TCW, AM, AC, ASC, FW, FG, FM, FC, BR, GH6, S3B, S3C, all 5-speeds, the Columbia 3-speed, the BSA 3-speeds (based on a Sturmey-Archer design) and the hubs in production when Sturmey-Archer ceased to be British-owned in 2001. Also included is information on the DBU and FSU accessories for use with hub dynamos.
