I've only ever seen two Seeley G50s In Australia over 55 years of attending road race meetings. One was owned by Craig McDonald, which he rode at the Mike Hailwood at Winton in about 1973. It broke a crankpin, and the motor got sold off. The other one turns up at Phillip Island and runs in Period 4. They would have to be the best ever British single cylinder motorcycle - this one is to die for ! : You must be logged in to see this link.
