The 1948 CFS 500cc/1000cc single seater

  • This well documented early car was built by Charlie F Smith with assistance from Don Parker and Jack Knight, as a logical development of Smiths earlier CFS special subsequently raced with great success by Don Parker as the Parker JAP Special.
  • The Chassis frame is very similar to, and incorporated lessons learnt from the development of the Parker CFS.
  • Since it was intended from the outset to race it as a dual purpose 500cc/1000cc car on the lines of the contemporary Moss Cooper Mk 3, it was “uprated” and incorporated a De Dion rear suspension with a ZF type differential.
  • Smith, who was also a successful Sidecar competitor raced the car in the UK and Europe in 1948 and 1949 including an entry at the 1949 Grand Prix des Frontieres at Chimay, one of two “V twin” entrants, the other being Stirling Moss with his Cooper twin. He finished in a creditable 5th place. Later in the 1949 season he was fatally injured during a Sidecar race at Blandford. After his death the car was taken over by Dickie Stoop for the 1950 and 1951 seasons.
  • In 1980 it was found as a very original rolling chassis missing its body panels and tanks.
  • It received a sympathetic restoration, the aluminium panels being faithfully reproduced by Rod Jolley.
  • It currently has a MK 1 8.80 JAP V twin installed, dry sumped with “big fin” alloy barrels, speedway “iron” heads, BTH magnetos and Amal T27 methanol twin float carburettors.
  • It has a correct period “dolls head” Manx gearbox and clutch and chronometric rev counter.
  • A 500cc JAP motor is included in the sale to enable the new owner to compete in both forms again.
  • Its period history as an 1000 should ensure renewal of its FIA documentation and eligibility to compete at prestigious levels as well as a 500cc Formula 3 car.
  • It has been unused for sometime and will require recommissioning.
  • See descriptive chapters in:
    “Specials” by John Bolster
    “500cc racing” by Gregor Grant
    “Iota” magazine Aug/Sept 1949
    Chimay circuit history by Andre Blaumet
  • Price £31500 spares available by negotiation.
