|EARLY PROMOTION PHOTOGRAPH CIRCA 1960 - Note early plastic Standard 10 Steering Wheel and lack of hinges for side screens.
|ANOTHER EARLY PROMOTION PHOTOGRAPH CIRCA 1960 - Note: static cycle wings 'flat' topped gearbox tunnel, early plastic Standard 10 Steering Wheel, lack of hinges for side screens, lack of air intake to side of bonnet which would indicate a BMC "A" Series engine installed and 13" x 3.5" Standard 10 wheels. (Photo Courtesy of John Donohoe collection.)
|ONE OF THE FACTORY DEMONSTRATORS - Note, narrow Triumph Herald wheels, chrome plated hub caps, Wingard stop/tail lights, Springhall wood-rimmed steering wheel with Lotus plastic centre, dashboard layout including indicator switch, Lucas L1130 front indicator/side lights and Lucas S700 double dipping headlamps. All this makes it a 1963 Lotus Super Seven 1500.
|ENGINE - Factory photograph of a 948cc. BMC "A" Series engine installation with twin 1 1/8" SU carburrettors ("America" spec.). Note: Cut-down damper housings to allow bonnet to clear.
|COSWORTH ENGINE INSTALLATION (factory photographs?) - With cast alloy Cosworth rocker cover, two 40DCOE2 twin choke Weber carburettors. The early type non-swirl pot coolant filler would suggest that this is a 1961 car with a Cosworth (Ford) Mark V 1340cc.unit developing 85bhp at 6,000rpm. Note lack of chassis plate!
|FIBREPAIR LTD's STAND AT RACING CAR SHOW CIRCA 1961 - Note lack of opening side windows. Is louvre grille at rear of bonnet for cockpit ventilation? Drum brakes and Lucas spot lights confirm that this is an early car (pre-September 1963).
|SERIES TWO KIT AS IT COMES! - Note: Twin Weber 40DCOE2 carburettors, Cast Alloy Rocker Cover, Spot and Fog Lights, shrouded Radiator, fabricated Exhaust Manifold, Drum Brakes and Springhall Steering Wheel make this a 1340cc. Ford 109E Cosworth Super Seven circa Mid 1961/September 1962.
|PATRICK McGOOHAN AND GRAHAM NEARN WITH THE CAR FROM THE PRISONER TV SERIES - This 1965 car has Elan type 4 1/2J bolt-on wheels but drum brakes which would suggest it was a Ford 105E powered car.
|FACTORY PHOTOGRAPH OF LHD MODEL [MOTOR SHOW CAR?] LHD says it is no earlier than January 1962, early type woodrim steering wheel says it is definately pre-September 1962. Note: Lucas 1130 Indicator/side lights and front number plate support. (Photo Courtesy of John Donohoe collection.)
|SERIES TWO ON TRACK - Lucas spot and fog lights and electric cooling fan would suggest a late 1962 car. Note also the crossply tyres. (Photo Courtesy of John Donohoe collection.)
The One and Only Lotus Type 37.
|CLUBMANS CAR - First shown at the Racing Car Show at the Horticultural Halls London in January 1965 the Type 37 was designed for the then new Clubmans Racing Formula. With its high specification came the high price of £1350-00 in component form, a lot of money in 1965. In the event only one was built which was in turn raced by John Berry, Lotus Sales Director, Peter Deal, Essex Racer and then by Tim Goss who finally in 1969 won the Clubmans Championship with the car.
|DASHBOARD - The purposeful dashboard includes chronometric rev counter, speedometer, ammeter, water temperature and oil pressure gauges. The lightweight steering wheel is of red leather covered aluminium similar to that used in formula cars of the day. Other items include racing mirror and curved perspex 'aero' screen. Note the battery mounted low in the passenger footwell for better weight distribution.
|ENGINE - The engine is a Holbay tuned Ford 116E 1500cc. unit with twin Weber carburettors and dry-sump lubrication developing 120bhp at 6,500rpm. A single dry plate hydraulically operated clutch connects the Ford close ratio 4-speed gearbox. The Austin Healey hypoid differential is enclosed in a Type 14 Elite light alloy nose and casing offered ratios of 3.7:1, 4.22:1, 4.55:1 and 4.875:1.
|I.R.S. - A more recent picture showing the fully independent Formula Junior type rear suspension with chassis mounted differential, fixed length drive shafts, aluminium hub carriers and parallel radius arms. Springing is by coil springs and Armstrong telescopic shock absorber units. Note the differential breather pipe and bottle.
|I.R.S. - Hydraulic braking is by 9" Girling disc at the front with AR calipers and 9.5" inboard Girling disc at the rear with NR calipers. The wheels are 13" diameter x 6" wide magnesium alloy Wobbly Web pattern shod with 500 x 13 front and 550 x 13 rear Dunlop Racing tyres. The fuel tank has a 8 gallon capacity. The fuel pump is Bendix high pressure. Steering is by lightweight rack and pinion.
~ A Restored Lotus Super Seven 1500 ~
|ORIGINAL SPECIFICATION - Narrow Standard 10 wheels and Dunlop C41 crossply tyres, leather spare wheel retaining strap, Wingard 1055 stop/tail lights, Lucas S700 headlights, all correct for this 1963 model. It would not have left the Cheshunt factory with the all-over paintwork shown.
|ENGINE BAY - Note: Single Weber 40DCOE2 on Lotus cast alloy inlet manifold, original throttle linkage and Swirl Pot Header Tank.
|DASHBOARD - Note: 3" Smiths Electric Impulse Tachometer, 2" A.C. full face Oil Pressure and Water Temperature Guages. 13" Springhall Woodrim Steering Wheel and plastic Lotus Centre and original Cheshunt factory Key Fob. The Gearknob should be the grey plastic item from the early Triumpg Herald and not the wooden Lotus one shown.
|RE-WIRE DETAIL - Showing behind the off-side of the dashboard with the scuttle off and the re-wire completed.
|AS ABOVE - Showing the near-side re-wire.
|DRY SUMP ENGINE - The only known Lotus Seven to leave the factory with a dry sump lubricated Ford Cosworth Mk IX 116E engine. The oil tank in standard from a Lotus Type 22 Formula Junior car.

|EXHAUST OUTSIDE THE CAR - Front and rear of the three primaries combine inside the car, then the two remaining pipes join before the silencer. (Photo Courtesy of John Donohoe collection.)

|LUCAS HF1849 HORN - Used on early cars (pre-September 1962). Mounted low on left hand engine mount (Ford engines) and high on right side of chassis in front of engine on BMC cars? (Photo Courtesy of John Donohoe collection.)
