Called Ace of Spades after the shape of the timing case cover, Lea-Francis’ own six was smooth running and good for at least 74mph, with an overall consumption of 24mpg.
The first chassis were very similar to the P type, but longer and in a heavier gauge; later the shorter P type chassis was used. A new gearbox (the Duo) fitted, as well as a new plate clutch.
Body styles included saloon and tourer, as well as coupés. In 1932 an enlarged version called the 18hp was made, but never went into production.
50 long-chassis and 26 short-chassis cars were built, of which only four long chassis survive (three in the Club), and probably 3 short chassis (two in the Club).
