Norton 750 850 Commando Rear Brake 'safety' Spring 06-4172

Norton's part number for this spring is 06-4172.  I believe it was only fitted to certain police models as a safety spring for the rear brake pedal, to keep it from falling in the event of a rear cable failure.  The spring is suitable for all r/h shift Commando, to my knowledge.  It's a little hard to mount, but looks splendid when done.

Stainless steel construction. Fit and finish guaranteed great.
