Riley 12/6 Grebe. (1933-34)

The Grebe was a 2-seater sports model which was listed in brochures, and a photograph of a prototype exists, but was it ever actually built as a production model? David Styles states in his book that the Grebe 'was dropped before more than one car was built'. Surely evidence that the prototype was the only example created - and this may have been little more than a non-operative mock up after all! It was at least given a chassis number, of 4/106, which was taken from the TT Racing model sequence, although the car is believed to have been completed separately, and not part of that models production.
