I have always been aware that Edward Turner did not design Triumphs first parallel twin, and I have often wondered why Turner has been credited with originating the parallel twin concept. It is a myth that has been perpetuated for so many years now that it is what people believe irrespective of what the facts are. It is often said that he had an inspirational flair for aesthetic design concepts, and the headlamp nacel has been cited as an example of this, however this design feature first appeared on Jawa motorcycles as far as I am aware. None the less there is no denying that Turner certainly had a considerable influence on the British motorcycle industry in general, and on Triumph in particular. Not always for the best as Bert Hopwood has implied, but that is another can of worms altogether.
