-JdK- This photo depicts Rob's mum as a little girl with two of her brothers on an ES2 Norton. The photo was probably taken in the early 1930s at a fair ('kermis') by a traveling photographer. The registration ('H') was issued in Zuid-Holland.
The Norton is a 1930 Model ES2 and appears to be brand new. Note the long chrome plated footrests and the speedo in the tank.
