JdK- Piet van Wijngaarden, Dutch champion at the 1928 Assen TT on his CS1 Norton. The photo shows the shape of the handlebars, the very long handlebar rubbers, the narrow mudguard and an awful front tyre! He seems to have wrecked his windscreen. The chap on the right is the Dutch winner in the 350cc class, Beverdam, on a Royal Enfield.
