I am in the process of putting the back wheel into the bike following a full strip of lock nuts etc. What stops the speedo drive from turning when it is on the spindle.

Have a look at Alans excellent cutaway photo.

The speedometer drive gearbox securing nut (No. 12) must only be tightened AFTER the axle nuts are tightened.

The cut-away picture does not relate to 1951. Completely different.

How do you assume that Alan?

The question was,

"What stops the speedo drive from turning when it is on the spindle."

....and the sectioned rear axle photograph answers the question, showing, and describing the lock nut!
Which is the same as on my 1951 machine!
