Searching the Internet I stumbled upon a French movie "Prends la Route", made in 1936, that features a lot of very interesting vehicles, not at least a few Nortons! The bike in the second black & white picture from top may be a 1930s model 18 or ES2, with the chrome tank and the right-hand exhaust. The bike in the other pictures is a 1929 Moore-engined CS1 Norton! Glorious pictures! Can anyone obtain a copy? The film was directed by Jean Boyer and produced by Raoul Ploquin.
