Riley 15/6 Falcon. (1936-37)

The second generation of the Falcon remained a coachbuilt body, However, it is thought that an attempt was made to use an adapted Briggs body on the 15/6 chassis. While there were less problems than with fitting the body to the later Big Four chassis, it was still not a succesful union, and it is doubtful if any left the factory.
It is not entirely clear how many of the 1936 season Coachbuilt Falcons were built, with very few survivors. Indeed, only 9 have been identifed, suggesting a production figure of 50-60. Whilst the Falcon was again offered for 1937, no 47F Falcon has so far been identified, and it is doubtful if any were built. The few '37 Falcon 6s known of carry 46F chassis numbers, suggesting they were simply slow to sell.
The Falcon thus slipped out of production almost unnoticed, after its revolutionary arrival in 1933. The New Adelphi was a much more up-to-date design, and quickly userped the older model at the top of the sales, with Riley naturally concentrating on their new star in favour of the old pretender.
