Sturmey Archer sprockets can be a real problem on early (pre 1951) hubs. Early 12-spline and threaded sprockets are difficult to obtain and early threaded sprockets are difficult to change.
I generally like to keep hubs in their original condition as much as possible, but sometimes a compromise is necessary.
Threaded Sturmey Archer sprockets use the same thread as standard fixed sprockets so it is possible to fit a fixed sprocket if an original threaded sprocket is not available.
It is possible to use modern Sturmey Archer sprockets (which are easily obtained and easily fitted) on a pre 1951 hub if you are happy to have the driver changed for a modern equivalent.
Changing a driver is a relatively simple task which you could do yourself. Alternatively I will very happily do the work for you.
