Pace Wim Oude Weernink, I'm not convinced that more than one car was produced. The car that appeared at Turin in 1906 is 17308, then owned by the late Gary Byrd and now in California. There are photographs of what appear to be three different cars; the show car, a car which appeared at Croydon Airport in 1927 finished in a single colour and a car with a modified roof to accommodate two rear seats that appeared in 1928. But Bruce Lindsay, who is pretty knowledgeable about the Airway, reckons that this is the original car converted at the request of the Australian who bought it. Certainly Curtis were finding it difficult to get rid of the show car, which was offered at a substantial reduction some weeks after the show, which might explain its subsequent respray/modification.
