An early example of badge engineering, these cars were made by Vulcan Engineering of Southport, with whom Lea-Francis were associated. The motor cars looked impressive, but were a finacial disaster for Lea-Francis as the twin-camshaft 1LFS engine was poorly designed and unreliable.

The twin overhead camshaft engine looked impressive too, but the 1LFS had flaws including inadequate lubrication, while giving no more power than a less complex design, and with low gearing managed only 60mph. The handsome bodies included saloons, tourers and coupés.
Lea-Francis spent much time and money repairing the first LFS engines under guarantee and fitting an additional oil pump. Vulcan later designed a much better two litre unit in 1927, the 2LFS, but it came too late to rescue the reputation of th emodel.
Of the 386 14/40s eight are thought to have survived (seven in the Club).
