Thanks Luddite for the photo but I have just rebuilt the clutch master cylinder with this SP1967 kit I had. The brake kit I am looking for is for the duel action cylinder that has 4 seals along with other parts. At the moment I have the clutch master cylinder rebuilt but thought a spare kit would be a wise move to have both cylinders re-built and ready to fit if needed. Perhaps I am looking too far ahead at the age of 81 years. Anyway thanks.
