The photo above was sent to me by an Australian, Leon, and depicts his approx. 1926 M18 Norton project. Leon casually informed me that he has five (!) 1920s Nortons, four of them flat-tank models and one of them that most coveted Norton, the M25.
It amazes me how many of these fine machines pop up in Australia. Only last sunday I was sent the photo below by another Australian; a very desirable Norton engine, a 1929 ES2 motor, note the dry sump lubrication. Holidays in Australia this summer!
