From "Instruction Manual No.17" 1956-1962. A book that rivals most repair manuals today. However, many things are assumed, like how to turn a wrench.
Remember those days well. Carrying a canvas bag full of tools every trip...stopping to replace the bits that had fallen off....bikes that refused to start once stopped. Pubs that refused to serve motorcyclists, Waterproofs that weren't. Ah, nostalgia... though of course its not like nostalgia used to be.
Trench coats that were wet, soggy old bike gloves, steamed up visors (if fitted) and that whoosh of cold water on every gear change!!
