Riley 14/6 Alpine Gamecock. (1934)

Riley 14/6 Alpine Gamecock (ADU29)

At least three of this model were built in 1933, for the Riley Competitions Department. They were registered as ADU27, 28, 29 and bore chassis numbers of 44T1733, 34, 35. Three more Alpine Gamecocks were supposedly built for the following year, but some now believe that these were the same cars heavily rebuilt with new registrations. Another Alpine Gamecock has been listed in the past as 44T1423 with a 12/6 engine, and carrying the ADU27 registration, however, this car is a faithful replica built in the 1980s and fitted with the historic number plate.
There is a suggestion that the Alpine Gamecock was also sold to the public, but despite there being a handful of 14/6 Gamecocks now identified, in addition to the works cars, there is some doubt as to whether any of them were factory built, rather than home made replicas, or Gamecock 9 bodies on the 14/6 chassis. At best, it seems that perhaps 10 examples were built, but probably less.

The competiton cars are:

  • 1933 - ADU27 - 44T1733 - Details on Replica ADU27
  • 1933 - ADU28 - 44T1734
  • 1933 - ADU29 - 44T1735
  • 1934 - KV5691 - 44T?
  • 1934 - KV5692 - 44T?
  • 1934 - KV5693 - 44T?
  • (KV5694-6 were 12/6 TT racing cars, later the White Riley and MPH prototypes)
