He actually has the mouldings for a little known 4/4 competition model the 4/4 Rutherford lightweight. It uses a complete fibreglass moulding for the entire car body and replaces all the body and wooden frame - sitting directly on the chassis. There are a few knocking about and tip the scales at about 550kg.
Many years ago i bought one of his lightweights, it even had a light thin gauge chassie. It was a work of art. Tried to use it for autocross racing but the short suspension travel proved unsuitable on grass. Sold it to Allan kennedy who used it for a time as a circuit racer.
