One lump ... or two?

-SG- ... is a subject we have had postings on before and here's another (click this link for the PDF)!  It comes from a 1975 newsprint cutting neatly folded in a secondhand copy of 'Past Masters of Speed,' which I bought in a second-hand bookshop over the weekend. It probably comes from MotorCycle News and makes interesting reading.
