-JdK- Markus contributes this post: "In Switzerland, close to where I live, I found an interesting Norton. It shows a heavily modified Model 18, which was first registered on 13.03.1926 (original documentation still available). Presumably, the owner made the conversion in the late 1940s and transformed the motorcycle with a rear swing arm. Also noteworthy is the covered girder fork with sheet metal, the self-made fuel tank and oil tank. Whether the lubrication really worked, I do not know."
