I bought these tools and Shop Manual for my 1970 Norton Commando 750 in 1972. Never used the tools, although they look used from setting around in a garage forever. They used to be a nice blue color. The one with the adjusting bolt is a clutch tool, the curved one for exhaust flange nut tightening, and truthfully, I can’t even remember what the two like tools were for. The shop manual is in excellent condition. Located in North Fort Myers.
