G-EBYY  Cierva C-8L (Avro 611)                                          (no known c/n)

                                   

                                       This rare photograph came from Australia's Civil Aviation Historian Society archives.
                                       G-EBYY was test flown at Hamble in 1927 by Australian aviation legend Bert Hinkler
                                       (no doubt why the CAHS has this image).  Hinkler was a test pilot for Avro, having
                                       remained in England after having served in the RNAS during WW I.     Anyway, the
                                       Cierva C-8 series were experimental autogyros designed by Juan de la Cierva based
                                       on Avro fixed wing aircraft fuselages, in this case the type 611.  This ancient machine
                                       is preserved in the Musee de l'Air et de l'Espace in Paris.
