Detollenaere sent these pics of his very original 1930 Model 18. Note the correct and unique 1930 paint scheme.
-SG- All the numbers (engine number 482xx, frame 419xx, magneto 77860, gearbox 106792) agree with the records. The bike was shipped to Hans Adam, the Munich Norton distributor, on 11/3/30. The extra comments column shows Chromed Tank, Bosch Magdyno and footchange (ie non-positive disc type on the gearbox rather than gate change on the tank).
