Here is an Auto Truck by Lister. Only posted it because it is classified as a truck. They are a 3 wheel device used widely in food markets and on farms and come with many different body styles.
Yes, those engines in the background sang beautifully during the day at Clarendon.
The early type Autotrucks like the pic have JAP motorbike type engines in them,and JAP engines are starting to fetch real money,meaning these machines are generally scrapped for the motor......they are 1 wheel drive ,and impractical off a concrete floor,or paved road......the 1 tonner has a 600cc sv ,similar to the Howard Gem,there is a 2 ton road version with a 750cc JAP V twin,these motors fetch up to $3000 in good condition.
