In mid 1964 James Rattenbury of Vancouver, British Colombia, contracted Huffaker Engineering, then of San Francisco , CA to build a Genie Mk. 12 sports racing car less engine and gearbox. Huffaker Engineering was known at the time to be a distributor for BMC (British Motor Corporation) and the builders of successful single seat sports racing and Indy cars. In 1965, due to the back order of Indy cars, his car is still not quite finished. On July 26, 1965, Jim Rattenbury takes delivery from Huffaker Engineering of a Genie Mark 12 chassis (chassis number 1001), uprights, rack and pinion, hubs, wheels, body panels (nose, tail, doors and windscreens), and Dunlop tires. Essentially a car less engine and gearbox. He returns with his Genie Mark 12 chassis number 1001 to Vancouver and completes the assembly himself of his new sports racing car. This is verified by the original 1964 and 1965 documents between Huffaker Engineering and Jim Rattenbury, Bill of Sale, delivery receipt and parts invoice. 

 As Quoted in the October 27, 1965 Newspaper Article “The Colombian”:

·        Completes the car with a mechanic friend.

·        Names his Genie Mark 12 the “Rattenbury Mk. 4” as it is the fourth car Rattenbury has built. 

The car is raced several times in the Pacific Northwest between 1965 and 1969. The car is wrecked at Westwood going end over end three times and landing upside down. The car is rebuilt and sold to Mike Barbour in 1969.

All owners are known from new with good documentation, correspondence, and photographs to tell the story of this interesting car. The owners of this car are James Rattenbury, Mike Barbour, Darryl Clarke, Tom Munro and Julio Palmaz. The maiden race was October 17, 1965 at Westwood. The car is raced from 1965 forward on circuits such as Watkins Glen, Elkhart Lake , Westwood, Mosport, Mid-Ohio, and Road Atlanta. It is even raced in the Can Am series in the late 1960’s. Excellent photo documentation from 1965 through the Can Am years and during the restoration are available.

The car was fully restored in 1995 with photo documentation. The car has the correct sized Genie wheels, correct steering wheel and was repainted its original color white. The engine, a Buick 3.5 liter V8, was rebuilt with a quad Weber carburetor setup, and original manifold. The engine was also converted over to a dry sump system. The fiberglass body was repaired and restored to the original style.
