Finally in a fairly acrimonious mood, Baker brought back the two-thirds share from Summit.
Baker also made an extra body, which was fitted with a Rover V8, motor and five-speed Subaru gearbox.
It had a very light aluminium monocoque chassis, Triumph Vitesse front suspension, a five-speed Heron/Škoda gearbox, and unequal length wishbones on the rear.
The Corvair engine was unavailable so a Daimler Dart 2558cc V8 connected to a Citroën DS 19 gearbox was installed instead.
Heron also specialised in modifying vehicles for use by the disabled, made small electric trucks, and spray units for orchards.
